AutoCAD MEP 2008 Unable to load a DVB file

[Fire Alarm]

Hello All,
Long time since I've been here. Got an issue I hope someone can help me with. I am trying to a .dvb file, and all I get is an error message from AutoCAD saying "failed to load project file" and "unable to unload the file" (gives file path). Is there a way around this, or could the .dvb be created in a newer version? Don't know if the latter matters, but figure I'd throw it out there.

Thanks to all who take the time to review this problem, and more thanks to those who might have a solution.

It might be corrupted. Then if it is, you may be able to extract out the code, and try re-building it or resaving it, and see if AutoCAD allows you to open it. Check all it's dependencies as well, so that one missing link isn't holding up the entire load. I had a coupe dvb go bad on me. You may be able to view it in Notepad to snoop around.

Thanks. There is only one problem. I wouldn't know what to look for.
