Thank you, Ibanez.

I tried to follow your suggestions, but things get worse. Now the game freezes at the first command, such as “fly this mission”, or open that map in full mission builder.

I envy you and all the happy Steam customers, but this sounds to me as a gross disservice as, for the moment, I paid for nothing.

I’ll wait for the release on dvd, hoping to have better luck, but I fear problems will start again with future patches.

I have one game via Steam that no matter what I did it would freeze on start in Steam. I literally tried every 'fix' in the book - nada. All my other Steam games worked fine but not that one.

Then I upgraded from XP to Win7-64 and it worked perfectly right away. Go figure...
