I typed in my product key, it all worked fine, but turns out i've used my product key too many times, so how do i type in my new one?

You most likely need to activate by phone. It should give you that option. Call Microsoft up and see what they say.

How many different machines have you installed this copy on?

[ellface]

5 or 6, i have a big family who ALL have laptops

No wonder, even the Home and Teachers version is good for only 3 machines.
Most of the retail Full Office versions are legal for 2 machines, one desktop and one laptop.

You need to go buy more legal copies.

And as we do not assist with pirated software, which is what it is once you go beyond the agreed amount you're allowed to install, I'm closing this thread. You'll have to buy more licenses to install it on other machines.
