Thanks for the posts, guys.
That's the problem, though, T.E.C.-Leader. Citing a couple of other posts I saw in doing a search on CODECS. The Ace Mega Codecs Pro package is what causes the problems that I'm having.
Am I reading you correctly?
Also, LOMAC does run on this machine. Flaming Cliffs doesn't.
BTW, D17S, my livelihood depends on how I keep this machine and a couple of others running (I'm a custom database programmer), so the idea of a re-format and clean install of XP Pro is _absolutely_ out of the question. The money this game costs is nothing compared to the risk involved in losing key files, etc. by doing that.
Besides, if this is the only game (and I have many, mostly flight sims - but several others including Dangerous Waters and Enigma) that has this problem, then I say it's a bug in the software and not in my machine -- particularly if others have had the same problem, which looks like the case.
But if anyone else has any other ideas, I'm all ears....
