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. .

You must use GTA:SA 1.0, something like steam version or anything other than 1.0 won't work.
Also make sure you specify the correct path of GTA:SA in the console of SA-MP which is used to find a server.
