We recently upgraded from version 11 to 13 and also upgraded to MS Office 2007. I can still query my Sage data into Excel have lost the tab for OLAPs however when attempting to a OLAP Cube I get the messge "Cannot connect to the data source 'The driver returned invalid (or failed to return) SQL_DRIVER_ODBC_VER:2.00;01000;Data files are wrong version;08001'. I have also lost the tab for OLAP Cubes that could be seen when I chose my Data Source.
