Printing UDF list error 65

I'm just trying to print, or at least view, a list of all of our UDF's from the UDF and Table Maintenance. I'm getting the dreaded error #65: Window element does not exist or already exists:CM_UDFMaintenanceListing_rpt. Tried renaming the existing file but that did not work.

Is there an easy solution for this or another way to view all of our UDF's?

Thanks!!
