I've just installed the trial, imported the Adventureworks full DB export and am trying to follow along with the video tutorial.
Connection seems to work OK and database is showing up. When I hit the "Preferences" gear icon though, I get the following error:
- Can't get fields from driver: Unable to cast object of type 'System.DBNull' to type 'System.Type'
The number of tables etc is showing up in the list, but I can't get beyond this rather unhelpful message.
Thanks for any help you can give!
