VS 2008 ReportViewer Problem

I have been beating my head trying to figure out why when I try to setup a new report I get this error.
Warning 1 Deserialization failed: The element 'TableCells' in namespace 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition' has incomplete content. List of possible elements expected: 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition:TableCell'. Line 125, position 32. 125 0

Any thought would be great.
