I was getting this error as well running the Sales Journal - the mentioned KB did not help me out. The error expression was *pcursor> 0 and *pcursor <= MAXCURSORS.
However, on reviewing the Event Log the error message indicated inadequate permissions on the view vs_SubXref. I corrected this issue but the odd thing is this was in a test DB - a copy of the production DB - and in the production DB the permissions were different.
Hope this helps someone else.
