Seven won't activate :<

Here's the deal.
I've installed windows 7 many times on this very same computer, only graphics card and HDDs have changed, multiple times that is.
Everytime it has been activated succesfully with same activation key but this time it just won't, I called the automated phone thing and gave it long series of numbers, then it said that it can't give the code, ok now I got new graphics card since last install (from gtx 260 to 480) but that shouldn't be a reason to decline my activation, even if i changed mobo it should still work with the call.

I don't know what to do expect reinstall later which sound's stupid because it should'nt be problem of my installation.

I've used same custom media that is automated install with same key everytime so it's not possible i've put wrong key and even if i did i tried to retype it.

And i'm not going to buy another windows 7.

What else can I do but to call real person who usually won't do shit.

What version are you attempting to install and where did you get it?

This sounds like a torrented copy of Windows...

Glad to hear that its all sorted out...
