don't s'pose you now how to get it back on the cheap
Office 2010 Home and Student edition is only £80 on Amazon, not exactly going to break the bank is it ?
Plus for that £80, the EULA allows you to:
you may install one copy of the software on up to three licensed devices in your household for use by people for whom that is their primary residence
Bloomin good value I'd say ! So off you trot to Amazon ....
