We have just updated to Payables 8.1B and I am now unable to import invoices from Excel into Adagio.  When I try to import invoices from Excel I get a partial screen that briefly displays the message Office 2000 End Use Agreement - Print EULA/Accept/Decline.  However it does not allow you to choose any of the options, that screen disappears and Adagio reports 
Error  Code: 1001 on to XLCreateEx.  
Previously I could import into Adagio with no problem.
