g6251346 Posted July 3, 2015 Author Share Posted July 3, 2015 I managed to answer the question myself.What you need to do is:1. Right click on dataset > Dataset and Query ...2. Change language to CSV3. OK Link to comment Share on other sites More sharing options...
ryne.gross Posted October 26, 2017 Share Posted October 26, 2017 I'm having an issue with the same error. However, I have also found the way you describe below for the solution but when I click 'Ok', nothing happens, no error, nothing. I can't even close the pop up box using the red x in the upper left corner per usual. The only thing I can do is cancel. Link to comment Share on other sites More sharing options...
