Files with an xlxs extension won`t open

I run Win 7 with IE 9 and Office 2007.I have recently had to reinstall Win 7 to cure a Windows Update problem then I reinstalled Office 2007. Since then files with an xlxs extension won`t open with a single or double click. I would be most grateful if anyone could advise how to cure this opening problem.Other files without the extension open normally.
