invalid product key

[jasonveeru]

I just installed Office X onto my mac. Everything worked great,
including the product key. Then I downloaded the latest update from
Mactopia. Now when I try to open any part of Office, it asks for the
product key again. I enter it in, but it tells me that it is an
invalid key. Is there any hope???

Situation 1: Was this a sealed copy? If you bought it opened or from a
secondhand source such as eBay, it's no surprise, as keys which are known to
have been pirated have been disabled. Sorry, you'll need to buy a licensed
copy.

Situation 2: If you bought your copy of Office X sealed from a reputable
dealer, it's possible for some reason your key was bad. You can request a
new one by calling Microsoft Product Support Services. For inquiries
regarding Office X (only), click this link for a phone number. You should
not be charged for the replacement key.
