Local cache database cannot be opened

Hello,

I have been using your program for a few days now, and I am experiencing a problem every morning. When I leave the office, I close all of my programs but do not turn off the computer. When I return in the morning and I start WebIssues, I get the following error trying to connect:

Local cache database cannot be opened.

Until i've restarted my computer, I cannot use WebIssues. I am running Windows 7 Home Premium with SP1 installed.
