启动时得到错误信息 "San Andreas cannot be found" (无法找到SA)
San Andreas Multi-player（简称SA-MP）并不是一个独立的程序。它只为GTA San Andreas添加了联机的功能，因此你需要首先安装有GTA San Andreas PC版，并且游戏版本是EU/US v1.0，其他版本如 v2.0 或者是 Stream 版 和 Direct2Drive 版本将无法运行。
我在 SA-MP 浏览器里看不到任何服务器
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!
进入 SA-MP 以后却发现是单人游戏
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. Download this patch that downgrades it to the right version. Click here to download the 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.
当我连接一个服务器的时候显示 "Unacceptable NickName" (不接受的昵称)
Ensure you are not using any disallowed characters in your name (use 0-9, a-z, , (), $, @, ., = only), and that your name is no longer than 20 characters long. This also could be caused when a player is on a server with the same name as you or if you try connecting to the server immediately after timing out.
屏幕停留在 "Connecting to ip:port..." (连接 ip:port 中...)
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.
我有安装 GTASA 的MOD，但是我的 SA-MP不加载
If it won't load then remove your mods.
从 SA-MP 上运行 GTA 却不能启动
Delete the gta_sa.set file from your userfiles folder and make sure you don't have any cheats/mods.
Most commonly it's an error in your server.cfg file. Check the server_log.txt and the reason should be printed out or in the crashinfo.txt file.
You will need to forward your ports! You can forward your ports by PF Port Checker Download it from: www.portforward.com If the ports are not forwarded that means you have to open ports in your router. You can check the router list at http://portforward.com/english/routers/port_forwarding/routerindex.htm
It has all the information about how to open ports.
显示 'Packet was modified' (数据包已被修改)This has been added as this error seems to happen frequently to servers. 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.
玩家们进入游戏经常显示 "Unacceptable NickName" (不接受的昵称) 错误但昵称是没问题的
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.
无法在 Windows Vista/7 上运行编译器
Run pawno.exe as an administrator.
