I recently installed the latest boinc version for Windows x86. It was running fine until now. When I start up the boinc manager, it says "retrieving system state, please wait" and then it quits. However the projects are running in the background. I am using Vista 32 bit OS. Vista problem reporting application of Boinc manager is listed below. I have removed and reinstalled the manager application and the problem continues.

Description
A problem caused this program to stop interacting with Windows.
