Excel workbooks open error in Guardian

[Emerson]

Hello, in Guardian when i try to open the excel workbooks that came with Bet Angel Pro, it gives me the error "Unable to open workbook " Library in old format or invalid, HRESULT:0x80028018 (Type_E_INVDATAREAD)
If i try to open the file outside betangel it opens but i cant connect it to the program.
Any sugestions ? thanks

PS: Im using Office 2010 and Windows 7 64bits

IMO the easiest thing is to change excel regional settings in Bet Angel settings to English (en-US) or to other language to match your Microsoft Excel language.
