Normally you can add a query as a new data source in Cognos PowerPlay (I'm running PowerPlay version 7.3), but when I try to do so I cannot select any queries from my Access database. The dropdown menu which normally shows the existing queries in the database is empty. When I add a table as a new data source it works fine, and all the tables are shown in the dropdown.
Previously it worked fine for queries too, but now it won't work. Does anybody know if it's a Cognos error or some system configuration on my pc that causes this error to appear?
