This is a new one on us.
The message is coming from Windows. It suggests a drive fault, a massive file, the drive offline...
Are you on a network? Could it be blocking BrainStorm?
These are all guesses. Marck is more familiar with the workings of Windows than I am. He's not around right now, but he might add something.
Can you give us more detail please? - Windows version? Save the file to another drive, see if that's okay. If it is please tell us filesize. And maybe the filename you're using. Anything at all, in fact that might help us replicate the problem.
