So I decided to reinstall GTA IV and EFLC. After a few problems with the game not running (downloading patch fixed) I started a new game but the mouse doesn't work, I can't move it at all.
I tried changing compatibility to XP SP2 and SP3 but mouse won't work.
I have now Windows 7 but I remember that I played the game a few years ago with Win7.
If needed: Windows 7 64b; i7930, 6Gb ram, GTX460 vga. (I've played the game with this hardware which I bought just to play the game )
Thanks for any help.
