I ran in to this as well. When it ran after I killed off everything in my status tray, I figured the culprit must have been something like Daemon Tools or AVG. I was pretty surprised that it ended up being FARR. 32-bit XP here, with a single NVidia graphics card.

It's quite happy to run alongside Autohotkey. However, the autohotkey bindings don't work within the game. This makes me think that Dirt2 is doing some low-level keyboard stuff that is conflicting with FARR.
