SP2 upgrade error message

After installing the SP2 upgrade to WIN XP PRO, I rebooted and found the following error message. “gearsec has encountered a problem and needs to close”. Originally I found gearsec in the startup tab of the System Config. Utility. I removed it from that window as per the instructions I receive from Gear Software. However, the error message continues to show on bootup. Gear Software ignors my email asking for additional instructions. I feel that it’s probably…but not sure, a registry problem.
I’m not qualified to edit the registry and hesitate to try.
Any suggestions or solutions will be greatly appreciated.

Thank you,
