Hi Nija, this error may occur for a number of reasons, it a Java error that can usually be corrected through reinstallation of certain applications. Firstly can you confirm that this problem is local to your workstation only? or are you logging in on the SD server? that is, I am trying to identify that this is isolated from the server.
Secondly are there any other applications or services running in the background on your workstation that could have effected your Java?
we have about 400 users on this site and I must fix this error at least a couple of times a week. It seems to occur on a totally ramdom basis irrespective of the users OS, role or hardware. I do not know why this happens but if you browse to the folder that the cache folder resides in,(something like "settings\application data\Hewlett-Packard\OpenView\Service Desk") and delete all the files (not folders) in this folder then the client should start correctly. You may want to take a copy of the views.dat file as that holds all the user's personal views.
This has worked for me many many times, I even talk the users through how to fix their problem over the phone. If anybody knows why this happens I'd like to know?
Have you tried to delete User.dat and create it again?
In these kind of errors as a general rule, keep a backup of everything under C:\Documents and Settings\PROFILE NAME\Application Data\Hewlett-Packard\OpenView\Service Desk\ and delete it.
Then run client again. If it run correctly, try to move back the Views.dat file (custom views). Generaly copy one by one any file under directory Service Desk (not the subdirectories) until you find what caused the problems.
Sometimes is a corrupted user.dat, other times srv.dat etc...
