I get the error "San Andreas cannot be found"
San Andreas Multi-player is not a stand-alone program! It adds multi-player functionality to San Andreas, and thus you need GTA San Andreas for the PC - it also needs to be EU/US v1.0, other versions such as v2.0 or Steam and Direct2Drive versions will not work.

I can not see any servers in SA-MP browser
First off, ensure you are following the procedures set out in the Quick-start guide. If you have followed what it says, and still cannot see any servers, you must allow SA:MP access through your firewall. Unfortunately, due to the large amount of available firewall software, we can not offer further support on this - we suggest looking at the manufacturers website or trying a Google search. Also make sure you have the latest SA:MP version!
Single Player Loads instead of SA:MP
YOU ARE NOT SUPPOSED TO SEE THE SINGLE PLAYER OPTIONS (NEW GAME, LOAD GAME, ETC) - SA:MP SHOULD LOAD BY ITSELF AND NOT PRESENT THESE OPTIONS. IF YOU SEE "NEW GAME" SINGLE PLAYER HAS LOADED, NOT SAN ANDREAS MULTIPLAYER.
Single player can load for 2 reasons - you have installed SA:MP to the wrong folder or you have the wrong version of San Andreas. If you have the wrong version it's easy to fix. . Click here to download the downgrade patch.
Sometimes the single-player menu will be shown, but SA:MP will have in fact loaded properly. To fix this you simply need to select an item on the menu then press esc until you're out of it, then SA:MP will proceed to load.
I get "Unacceptable NickName" when connecting to a server
Ensure you are not using any disallowed characters in your name (use 0-9, a-z, , (), $, @, . and = only), and that your name is no longer than 20 characters. This also could be caused when a player is on a server with the same name as you (which can happen if you re-join a server very soon after timing out or crashing). Also a Windows server running SA-MP with a uptime greater than 50 days can cause this bug.
Screen sticks at "Connecting to ip:port..."
The server could be offline, or if you can't connect to any server, disable your firewall and see if it works. If it does you must set up your firewall properly - go to its website to find out how. It could also be that you have an old version of SA-MP, download the latest version from the SA-MP download page.
I have a modified GTA: San Andreas and SA:MP won't load
If it won't load then remove your mods.
When launching GTA with SA:MP it won't start
Delete the gta_sa.set file from your userfiles folder and make sure you don't have any cheats/mods.
The game crashes when a vehicle explodes
If you have 2 monitors then there are 3 ways to solve this:
- Disable your 2dr monitor when you play sa-mp. (Maybe not so smart if you like to have the monitor on.)
- Set your Visual FX quality to low. (Esc > Options > Display Setup > Advanced)
- Rename your GTA San Andreas folder (e.g. to "GTA San Andreas2") (This often works, however sometimes it may stop working again so you need to rename it to something else.)
Server instantly crashes when started
Most commonly it's an error in your server.cfg file or your gamemode is missing. Check the server_log.txt file and the reason should be located at the bottom. If not, check crashinfo.txt file.
Server is not working - firewall is disabled
You will need to forward your ports to allow players to join your server. You can forward your ports using the PF Port Checker. Download it from: www.portforward.com If the ports are not forwarded that means you have to open them in your router. You can check the router list at http://portforward.com/english/routers/port_forwarding/routerindex.htm
It has all the information on how to forward ports.
'Packet was modified'The error commonly shown as:
[hh:mm:ss] Packet was modified, sent by id: <id>, ip: <ip>:<port>happens when a player times out or is currently having connection issues.
Players constantly getting "Unacceptable NickName" error but it is valid
If you are sure you use an acceptable name and the server runs on Windows then try to change the compatibility option of the samp-server.exe to Windows 98 and it should be fixed after a server restart.
Windows servers with high up time may also cause this issue to occur. This has been noticed of around 50 days of server up time. To resolve it, a reboot is required.
