database not found message

I'm working off my hard drive. Specify the results folder asa subfolder of the working directory. Run mesh and analysis. Go toview the results and get "database not found" message. Get the samemessage when viewing the mesh. Seems to be random. I can rerun thestudy with no changes and get results. I've had this problem beforebefore with other models so it's not just this model. I'm usingSWx64 2007 sp2.1 CW sp2.0
Any help would be appreciatedSolidworksSimulation
