First of all, I'm a big fan of you Thumper and have been using your MS Office for the past few years. However the software suddenly stopped working today with the error: "Microsoft Office cannot verify the licence for this product. You must repair the Office program by using Control Panel" and I have been unable to use it since. I've tried repairing it, installing it, uninstalling it and installing it again. Nothing works. Please help me fix this
