Fix Pack 3.3 Problem

I've just loaded Fix Pack 3.3 and when I attempt to open an existing Dashboard file, Excel opens and I receive the following message: "Microsoft Visual Basic File not found". I then get the following message from Xcelsius: "An error occurred while communication with Microsoft Excel. To prevent further data corruption, Xcelsius must close". I'm running Xcelsius Engage on Windows XP.

Anyone else have any ideas or experiencing similar problems?
