powerstore 2, menu writer not working

I am on a Windows vista machine, using Dreamweaver CS4 with Menu Writer 2.0.3 and powerstore 2. I have the store set up, haven't been using a test server, I basically upload the pages and see if everything works okay.

We initially had no problems at all using menu writer to change the menu in powerstore 2. Site is up and running, database works great. BUT, now if I try to access menu writer to change anything at all on the navigation bar, menu writer gives me an error code (attached) and goes into a loop that doesn't allow me to get out without using task manager to shut down Dreamweaver completely.

It says it is a database error, but the database seems to be working fine. We only get the error when we try click try to actually use menuwriter.

If you need to look at the page itself, please create a ticket and I will submit the url privately.
Thanks,
Michelle
