V4RB2 How to Diagnose a Corrupt DB

[Bob Keeney]

We received a database from a customer this weekend that cannot be  
opened in RB.  Every time we attempt to open we receive a hard crash  
and get the following crash log:

As you can see, it happens in the open function.  The database is  
fully encrypted (both data and structure) and we can't open it in  
studio.  How do we diagnose what the problem is?  Better yet, how do  
we get the data out for the customer?

We are desperately trying to find answers.  If you have any idea,  
please email me direct as I'm in digest mode.

Thanks,
