Hi,
I'm using Excel 2013 for building a PowerPivot model. Currently 2 table are inserted (txt files) which are related by a unique customer ID.
At for me random moments the connections with the files gets lost and no data is shown. Nevertheless, the number of rows and column headers are still visible. If I go the 'existing connections' and choose 'refresh' I got the following errror: "We couldn't refresh the connection, please go to existing connections and verify the connect to the file or server". If I try to edit the data ('edit connection') I see immediatly a preview of the date. But when I choose save I receive the following error: "unhandeld exception has occured in a component in your application ... The server object is not connected."
Remarkebly I never had this problem with the same data in Excel 2010. Anyone an idea what could cause this problem and a way to work around this?
Thanks in advance,
Rolf
