froze up after completing analysis

I am running an analysis with about 450,000 elements. The analysis finished (after > 100 hr), and then I clicked the save button and solid works seemed to freeze up. I closed the program and opend the assembaly again after leting it sit overnight. There is a .cwr file in the location where i saved the results, but when i try and acces the results in cosmos it says "database not found". Is there any way I can open the database?

Thanks
