Strange YOU problem.

I just upgraded from 9.2 to 9.3 and now the susewatcher applet won't connect to show me whether there are updates or not. When I open susewatcher it says YOU status - Couldn't connect to update-server. When I click on the show last log button this is what I get: online_update -k -s Error retrieving patches: ERROR(You:File has invalid signature.)[Patch: fetchnvidia.sh-52062] If I start online update I am able to connect and download and install patches. I searched google and found nothing. I also tried rpm --rebuilddb and that didn't help either. If anyone's seen this I would appreciate some help. Thanks, Andy
