So, after I finally managed to install & configure my new PC, I installed GTAIV. EVERYTHING IS ORIGINAL, no cracked/illegal stuff. All works fine on SP including IV's multiplayer, so I downloaded and installed IV MP (RC1 I suppose?). When I try to launch IV MP, it simply doesn't do anything. I hear my PC starting up (noice starts), but then it fades away and nothing happens. Has anyone a solution for this? I really was looking forward to play on IV:MP, something new etc. but now this popped up and have no idea how to fix it... I tried looking on the internet: no results. I tried running it as administrator/through different compatibility modes but nothing seemed to work. Help would be very appreciated. Oh and, my GTA IV has the latest patch, the 1.0.7(...) one.
