Please help me!

So I recently bought Windows 8.1 Full Version from Best Buy and all, and I have my product key. I downloaded a trial version of Parallels and used my key onto that. 14 Days later (the length of the trial), I decided I don't really like Parallels, and I would rather use Bootcamp.

The problem is, after completely uninstalling Parallels from my Mac, my Windows 8.1 product key no longer works. Whenever I try to activate it in Windows, it keeps telling me "The key didn't work. Please try again, or use a different key." Am I no longer able to use the key? What should I do? I really do not want to buy another one.

If you try it though, It'll direct you to call them. Which is what you would need to do.

Yes, call and you'll be all set. I had to do this, because I needed to reinstall my VM and I already activated the old VM.
