#7 Access violation when trying to resave project

[Vex]

I created a couple of tables, and saved out as xml to a
file, all worked fine. Then I added several more tables
and added a few relationships. I then went to save
again, selected the same file as I originally saved in
and hit okay, the following error occurred:

"Access violation at address 00402228 in module
'myDBExpert.exe'. Write of address CC1AF828."

The program was still running, but any attempt to
access the following, produced the same above error:

Open
Output (Any option)
Relations -> Edit
Tables -> Add
About

Checking the xml output file, and it hadn't resaved the
data (only data present was from the original save).
