I got GTA IV from Direct2Drive this weekend, installed it, and entered my activation key, but I keep getting the wobbly cam and leadfoot errors. After googling it, I removed the GTAIVGDF.dll file, which fixed it for a while, but when I tried playing it again today, they came back. Can someone help?
I also want to be able to play online, so I don't want to do the RGSC offline thing.
EDIT: I fixed it by revoking the activation code, and then reactivating the game.
