Is there an issue with WPMU Dashboard?

These sites redirect to WPMU Dashboard. Not their respective dashboards.
http://www.carpetstorect.com/
http://ctbestrents.com/

I deactivated the WPMU Dashboard and Was able to get into these sites But when I did ALL my content was missing. i.e. posts, pages, media, etc.
So now I reactivated WPMU Dashboard and having the original redirect issue. Any help to trouble shoot this would be much appreciated
Its only with these sites.
