client_state.xml Broken?

One of my computers, Core2Duo, ID: 3324167, seems to have a problem. For some time now Ghost Detector v1.05 says that the "...Server indicates less Work Units 'In Progress' than client_state.xml thinks you have on board...Aborted". I believe the problem started when I had to reload my Vista OS. Despite my best efforts, BOINC insisted on aborting all the work units still in progress for all my projects.

For the second time I have set my Core2Duo to "No new tasks", let all the SETI units complete and report, then reset the project. After the first time the reset failed to resolve this, I identified several orphaned work units that were still sitting in the setiathome.berkeley.edu project folder. I deleted them manually. The problem persists. Is there something I can do to correct this?

Ghost Detector works find for my other computers, and it used to work fine for Core2Duo, so I do not think it is an error within Ghost Detector.

If it will help, I can provide a copy of my client_state.xml file.

Let me ask a slightly different set of questions.

First, how can I determine for certain that my client_state.xml is showing -more- tasks on board than Berkeley believes are in progress?

Second, if there is truly a problem with my client_state.xml, then how would I be able to repair it?

Third, if all my units are processed, uploaded and reported, what impact, if any, might a repair or deletion of my client_state.xml file have on either my specific computer or my account in general?

Thank you for any insights you might be able to provide! :)

Hi Claggy,
Both BOINC Manager and SETI at Berkeley show no tasks in progress remaining for my Core2Duo computer. Is there a field in client_state.xml that might indicate that there are still tasks in progress remaining on my computer?
