My coworker reported problems trying to open our database...I hoped it was simply "locked"...no such luck.  I'm getting the following messages in the admin log:

Failure while opening application w:\ masterdatabase.db
Failure to read a record at 833
Failure while loading application w:\masterdatabase.db

Initially there was a message saying that the files had been marked "read only"...I checked the individual files and, indeed they were.

Any help appreciated.

Thanks Ray.

My best guess is that "we" are still having an issue with accessing Sesame database files from a network drive while not running client/server...I'm still waiting for approval and server space from our IT dept.  No problems from my workstation though...we do have IT monitoring his network connection-trying to find anything in the way of problems there.
