Shawn,
This may be a couple of known things; one is related to your specific installation (may have become corrupted if you did an upgrade from a previous version, especially if you upgraded from Beta?) Or, it may be related to a known SQL Server compatibility bug for which a hotfix will shortly be posted. (Problem with some Microsoft DLLs that get updated if you install SQL server).
If you have SQL Server installed, try looking on these forums for a patch that should be posted within the next 2 days. If not - please contact me directly, as I'd like to get someone on my development team to help look through your installation and see what the problem is, so we can fix this properly.
Mike
