Moving OpManager 8 instance to Windows 2008 R2 and SQL 2008 R2, No widgets available!

Hi there. I'm running the latest version of OpManager 8. I'm attempting to perform a clean install on a Windows 2008 R2 server using SQL 2008 R2 Express as the DB and when I log in, no maps or widgets are visible. I also see the following error in the log files:

08:32:24:960 AM com.adventnet.db.persistence.metadata.MetaDataException: Illegal value specified for a BIGINT column: #(select TYPEID from WidgetType where TYPENAME in ('@(widget.typename.general)','General (Map View and Others)'))

We were previously running well on Windows 2003 x86_64 using SQL 2005 Express.

Thanks in advance for any input you can share..
