Hi Guys like every one eles this was destined for the bin with all the troubled it caused aaaaaggghhhh i done all what other have advised to get this going but to no avail it really is hit or miss basicaly with what driver is best for you CCC manger(and it cos more problems with other games) is a waste of time guys you only need the driver 10. 9 for 64bit for 5770 graphics card in the end worked for me, i get odd tearing but playable so if you got the same card give it a whirl with a clean install download first rember before uninstalling your driver GLuck http://support.amd.com/us/gpudownload/windows/previous/10/Pages/radeon.aspx?os=Windows%20XP%20-%20Professional/Home&rev=10.9#2 just go individual driver download
