I'm running PowerPivots in Excel 2010. When I renamed the sheets in the PowerPivot window and then went back to the related pivot tables and refreshed them I got the following error and the pivot tables where disconnected completely from there data source and destroyed. I read a related post on this in MSN that indicated that refreshing the data sources in the PowerPivot windows resolves this problem, but it didn't in my case. Can anyone suggest the protocol for resolving this?
Thanks,
