that is weird Drano...haven't ever seen that happen. here comes the dumb question, what is your installation path for aces high?
Root of my D Drive. My OS is on C and that's a SSD so it's the only thing I have on there. I remember this happening once before a while back. Funny how all the other .exe's in the folder (ahfilm and mission editor) are there but only the game .exe is not.
I backed up my stuff, downloaded the full version of the game and re-installed. It's fine now but is annoying that this happened. I don't recall it happening when I've downloaded a patch from HTC and installed that manually. <shrug>
