PVCS Crashes on check-in Process.

Hello,

I have Installed the version PVCS 8.6.3.0 and I have this only as Desktop client. i.e. no Version Manager File Server has been installed. Post setting up the Project DB and Projects, I am able to perform all the Actions such as get, check-out etc., except check-in.  I am checking-out a module (in administrator mode) to a work file location, make changes and perform a check-in, PVCS crashes. During the check-in processing, it gives me a pop-up message "Java Version Manager GUI Application has stopped working". When I click on the problem details, 

Problem signature:
Problem Event Name: APPCRASH
Application Name: pvcsvmnt.exe
Application Version: 8.6.3.0
Application Timestamp: 6011ef4c
Fault Module Name: StackHash_1acc

Post this the application closes. What happens is that in the archives folder there is a file created with the extension *.-sem (at the time of check-in) and until this is delete, I am not able to unlock the file again. 

Do note that, this happens only when I make changes to the checked-out file and check it back in. When I simply check-out and perform check-in, with no changes to the module, there are no issues in the system. 

Would be glad if help is provided.
