That is the exact message I got when I flashed my phone but forgot to hard reset. Get PIM backup to back up your calender, contacts and text ,if you want to. Save the backup to your storage card. Then hard reset you phone. Delete partnerships in Active sync. Put the backup back on, then sync with your PC. That is the fix I used just last night and it worked perfect.
Edit: Oh well flyers beat me to it. That is my suggestion as well. Gues I need to take a typing class to beat flyers.
