One user here had this issue. Installing the fix was not enough. He re-downloaded the .odc file, opened it in Excel. At that point he could create a new pivot table and confirm the connection was ok. Then copied this worksheet to the original Excel report. This prompted him to overwrite the existing connection with the new one, which he accepted. Then refreshing the original Excel report worked.
