Each time I try to run Microsoft Office Starter 2010 I gen en error message:

Translation: Microsoft Office has encountered an error with licensing and must be shut down. If the problem will continue to occur, uninstall product and install it again.
I tried uninstalling and installing it again, but error message still occurs.
My laptop is Toshiba Satelite C660-1M4. It had preinstalled Windows 7 and Office 2010.
