No i'm not using his version. I'm using my version on his PC. I install mine, upgrade mine to 1.3, all on his comp. Then i burn the whole dir on a cd and copy it back on my comp. That way I only use my official opf cd, but i do the upgrading on my friends comp and after that i take my original game back home, together with a copy of the part of the game that's on the harddisk

Could this work ? I,m planning to take my original game to a friend, install and upgrade on his PC to 1.3, then burn the whole opf directory on CD, take my cd's home, copy the dir to my hd and start playing opf v1.3 What do you guys think. Possible or not? Sven

Yes it's always the same message. I just tried upgrading to 1.11, and it worked fine.

Yes I have a via chipset in my mb. I downloaded the 4in1 drivers from via and installed them, I also unchecked the DMA option in CD-drive and HD, but still the same error.

This is what I get when running the official 1.2 patch. MB = KT7A Athlon 1ghz Verifying Operation Flashpoint, version 1.00... Error found in file OperationFlashpoint.exe (1ba7e11e!=1f2729c1) Error found in file OpFlashPreferences.exe (a69fd2cb!=d9390c08) One or more files in game instalation are modified or dammaged. Reinstall game from original CD disc and try again.
