Hi all just wondering if anyone else has experienced this.

I have a PowerPivot file I created in 2010. Worked as expected.

Last week I upgraded to office pro 2013...And therefore had to upgrade all of the PowerPivot files I have had generated thus far.

I had no issues with all of them except for one.

Whenever I try to do a refresh it never returns, there's no error - nothing it just runs saying reading data but nothing happens. Eventually I have to kill the excel file, Like I said this file refreshed without issue in 2010.

Has anyone else had this issue and was able to resolve this?
Any info would be appreciated

thanks
