I am getting the dreaded "An essential sheet cannot be found in the current map data set." again but this time i am a little stumped.. I'm using a workstation installation of 6.30.

I can add polygons to the map but the error appears then i try to run the wizard with a polygon filter set. I immediately get the error.

The workstation settings are all aligned to the same server. The folder is accessible and writeable (i can create files in it) and i can add polygons to the map as noted above. I have tried resetting the map and creating entirely new ones but nothing is working.
