SupportCenter Won't Load - Database Corruption??

We are unable to get SupportCenter to load. SupportCenter starts to load, but after a couple minutes the loading screen disappears and support center is not running.

We have rebooted the server numerous times, but SupportCenter still won't load.

I found the following message in the sp.err file that is occuring each time we attempt to start support center.

Any help on getting this resolved would be greatly appreciated.

Thanks.
