PWA "My Tasks" unexpected error. - beto697

We have had Project Server 2007 (SP1) installed for a couple of months and
working  happly... until now!!...

One user, out of 9, is now having problems, when trying to open the My Tasks
page it gets:


Web Parts Maintenance Page: If you have permission, you can use this page to
temporarily close Web Parts or remove personal settings. For more
information, contact your site administrator.
Troubleshoot issues with Windows SharePoint Services. "

When I go to the "Web Part Maintenance Page: tasks" as suggested, I can
Reset it for the specific user, but still doesn´t work.

I think I have discarded a WebPart problem. All other users can open it
without problem, I removed the WebPart and added it again (for all users) and
no change, I exported the WebPart and imported it and still no change.

I guess it could be a data problem with this user's tasks, however, I opened
all projects the user is assigned in, checked them (no obvious problems at
least) saved and publish them again. Still, all users can see their tasks
except this one!.

Any suggestion? Is there a way to check what the heck is PWA looking for in
the database when this happens? Any other idea?....

Help is well appreciated!
