Problem loading s/s into Presentation design 2011

Just uploaded Presentation Design 2011 with intent to start with an existing simple RoI calculator.

I go to "Model with Spreadsheet Data"

Get Error message "Server Busy"

Unable to load in s/s

Do i have to build the s/s within Xcelsius or can I import?

Excel 2010

Presentation design 6.0.0.0 Build 14.0.2.364
