Drill Through issue

Hi,

I've created a drill-through query and put it in the QueryFiles folder, added the drillkey in the Account dimension and set up the table in Admin as per attached. However, when I try to drill through in a report, I get the message "Could not find file \\PLAY\Osoft\Webfolders..." although to me it looks as if it does exist in that folder.

Any idea what could be wrong? (BPC10 MS, SP13)
