Windows, It Irks Me Again

[ChuckMajik]

Not only did it just randomly screw it's arse and force me to reformat.
But now it won't let me activate it, keeps telling me the product key is incorrect.
But the the key is correct, and it's typed in properly.
Need solutions, help me men!

Give a call to MS. Also if youve reinstalled a certain number of times, I think you have to get a new key.
