Microsoft Outlook 2003 will not open

Somehow my POP Outlook client (I am not connected to an Exchange server) got corrupted and refuses to open successfully.

I have done a system restore with no impact on this problem.

I did not install any plug-ins to Outlook in between the time it worked and now.

I completley uninstalled Outlook and reinstalled it to no effect.

When I open Outlook in Safe mode I get the same problem.

Please help!
