after I install Map pack
click on a server, it starts to connect me, after it loads the game, it gives me this error message:
GTA:SA:MP: gta_sa.exe -fatal application exit : Internal error:23702744. What does this mean?

what do I do? (I can Play single Mode and Not problem but I can't onlinemode)

What do you mean by "map pack"? If you mean a mod that changes your map, it's probably that that's causing your SA-MP client to crash. Try removing it and trying again.
