database error - connection strings?

HELP PLEASE! my hosting company completely messed up my wordpress installation and they arent offering me support. they have been dragging me along for 4 days now and nothing is gettting fixed. when i went to my domain (moxietoday.com) it said eerror establishing a database connection. when i go to moxietoday.com/wp-admin it says databases may need to be repaired -- i clicked the repair button and it told me to post this on the support forums....
