I have a brand new Sony VAIO notebook that had a trial version of Office 2007
Small Business installed. I had also purchsed a medialess lecense for Ofiice
Professional 2007.

Sony tech support told me to download a trial version of Office
Professional, remove the Small Business version from my computer, and use the
purchased key to activate the trial version of Professional.

But the trial Office Professional does not accept my key, and I do not know
what to do now.

HELP!
