Hi guys
the same things , I did my graphic card update and then i had the same problem...
I uninstall and reinstall IV MP and the same thing happened..
I restore my old version of my computer ( my PC did a save before the update) and it works ...
So i'm playing with a outdate version of my graphic card ! and i can't play other games who need the latest version ( BF4 , NFS Rivals..)
So anyone can fix it ? or if someone had a solution :s
Thank you for your attention
Loïc

NB: I don't have the Steam Version of GTA IV , so i don't thing it is related to Steam
