Hello all, I recently upgraded from vista premium home to windows 7. So far no problems. I also have office 2007 small business, but downloaded the office 2010 beta version for free to try it out. Every time I try to open a new document, I get an error message. (Office application version does not match) after I close the error tab, the new document opens fine. Does anyone know how to get rid of the error message? Thanks for the help.
