file corruptions on open of a viso dwg.

[Jerry]

When I open a viso drawing...I get an error 5392 Corrupt file. What can I do
to fix??
I just upgraded from the technical refresh to the new trial version. I was
working on the file for a few hours...saved it. When I tried to open the
same file the next morning . It gave me this error

Since you are using 2007, you could try opening in a machine with 2003. They
use the same file format.

The file may just be corrupt, and there's nothing that can be done other
than to recreate from scratch, unless you have a backup of the file.

Also, you can try everything in the KB article
http://support.microsoft.com/kb/826418/en-us. If that doesn't work, read the
"Methods to try to help prevent damage to drawings" on how to prevent in the
future.
