[mhd75xv2]

Hi, I got a problem with my SA:MP. I launch it and have no problem ans when I double click to get on server and click on connect well nothing happens, I reinstalled both GTA and GTA: SA MP and still have this problem :( HELP!!!!

[edit]

Can you give anymore specific details? Operating system, etc.
Do you have Vista? Have you tried changing compatibility mode of gta_sa.exe?
