Error Executing reports

I have been evaluating the Team Foundation Server Beta Refresh 3 without any problems, but have recently installed on a new server the RTM Trial Version, but the reports don't work.

For report Bug Rates:

An error has occurred during report processing. (rsProcessingAborted)
Query execution failed for data set 'PriorityParam'. (rsErrorExecutingCommand)
Query (19, 3) The ALLMEMBERS function expects a hierarchy expression for the argument. A member expression was used.

Any ideas?

Thanks

Giles
