Error opening file

Hello, my co-worker received this error message when trying to get into his file.

He happened to be in the file when his network cable was switched from one outlet to another. Now he can't get into the file or even reference it into another drawing. I tried the -VRG option with the program shortcut, but it just causes Microstation to crash. I think the file is toast, but I wanted to see if anyone else has had this happen and what they did to resolve it. We have a backup macro that makes a backup copy of a file when you get into it, but unfortunately it made a backup of the corrupt file when he tried to get back into the file, overwriting the last good copy he had from today.
