Excel spreadsheets from a document service(EdgarPro) won't load. If you

Spreadsheets at the paid service EdgarPro won’t load. There is only blank cells and some broad bands of gray. Other internet spreadsheets of exactly the same type will load. For instance if I try to download the 10Q excel spreadsheet for Office Properties from EdgarPro I get no results. If I go to the company site and use their spreadsheets made available to investors(same type of SEC document) it will work. Any idea of what causes this?
