I have bought EU version of OPF (1.00) and I cannot upgrade: CRC error, file corrupt, CRC, file corrupt...
I have tried all solutions: re-install windows, change windows version, uninstall ASPI, disable HD DMA, remove all unnecesary hardware, upgrade BIOS, upgrade drivers, etc. etc. etc. etc. Doesn't work.
I emailed to CODEMASTERS (aka CODEF*CKERS) and they sent my questions to my local supplier. They have no idea.
I should use cracked games, instead of buying? This is the fantastic original/registered software???
