I tried both "Verify the User Profile Service " and "In-place Upgrade" and both didnt work for me. What did work was booting to Safe Mode and running a System Restore. I think it was caused by a DirectX or Shockwave update. Thanks for the help .

I also found the following in my application event log: Windows cannot copy file C:\Users\Default\AppData\Roaming\Macromedia... This was probably due to a recent Flash update that set security on the folder. My fix was to reset security for all children of the Roaming folder.
