[Dxbase] DXBase Broken - Cryptic Error

Wed Jan 5 18:40:38 EST 2011

After I started DXBase this evening it started returning the following 
errror:
Reserved error (-1601); there is no message for this error.
I get this error in return for attempting almost any action, including 
initializing tables and shutting the program.
The only way I can exit the program is with Ctrl-Alt-Delete.
It was OK yesterday. The only thing I did when I started up was to find 
a couple of QSOs to record receipt of a QSL Card. When I went to verify 
what I did the error started happening.
I have replaced all of the files from a recent backup that have changed 
in the last 24 hours but there was no help there.
Now what?
