Can I still make my Microsoft Office 2010 Starter work again after an Office trial I installed has expired?

Do you have a pre-publisher trial backup ?,
Is your machine an OEM with a recovery partiton or recovery disks ?, these will return you to factory settings and all the software that came with it.
You can then reactivate 'office starter', update all software reinstall programs and copy your documents, etc back onto your computer.
Sorry I could not think of or find an easier way.
