I upgraded to Vista Home Basic about 3months ago and I loaded Office 2007 onto this laptop about 3 weeks ago and a very sinister problem has just begun with Excel 2007 only.

Excel 2007 was working fine until I started receiving an error message when try to open a spread sheet... the error message is "Microsoft Office Excel has stopped working" followed by a "close program" option.

This is a HUGE problem for me. I have been to several blogs/message boards and have not found a fix. I have been to the Microsoft website and cannot find a fix there either.

Could some one please help me?

Thanks,
