Thank goodness for CodeLobster for helping me solve this issue. I had to add application/ms-excel to the mimes.php csv array because for some reason my Firefox browser was passing this along. IE still uploaded the files with out issues. The only thing I can think that was causing this was I started using PHPExcel and did not use IE at all. Just an FYI for anyone else.
Thanks,
Bruce
