I just installed Windows 7, and my steam folder is on a different drive. I just moved from XP, so I downloaded the installer, and installed to the same directory all the steam files are. It boots up, but every time steam starts, it tells me, "You do not have enough disk space available to run this game. Please free up some disk space and then try again." The thing is, I'm not trying to run a game, I'm starting up steam. I have ~12GB free on that particular drive. I never got this error on XP. Any ideas? I've already deleted clientregistry.blob. No dice.
