Congrats, key sent !

I get an error message: Duplicated Key. Key alredy used in another account.
-.-

Sorry, I made a mistake, new key sent !

Same error

Hello, it's impossible, one of the two keys is good, I just checked.

This key V8AT4-XYHPY-0033D
Gives me this error (is in italian, I translated it):
"Duplicated product key. This product key has alredy been activated in another account..."

Try sending me the first key, but i swear it was the same error

I don't understand, I send you again the key from humble dumble pack.

I tried...same error

I send you a new key, this one is good normally.

it worked... thanks a lot
