After uninstalling SW 2010 beta 1 I started having this error message when I start SW. Has anyone seen this before? Does anyone know how to fix it?

Things I have tried:

Fresh install

remove SwDocumentMgr.dll, and did a repair

uninstalled PDM Workgroup add-in and admin, reinstalled

Turning off the PDM add-in in SW -- This resolved the issue, but it came back as soon as I turned the add-in back on.

Thank you

Brian
