Validation Code not working

[Angelman180]

Hello.
I own TrackMania 2 Canyon, Stadium, and Valley on my account, angel_cruz_canyon, and I do have all three of those keys.
My account is not validated on my computer.
When I go into the player page to create a new validation code, every single key works, and gives me a code.
But they don't work in ManiaPlanet when I try them.
It comes up with an error, saying "Wrong validation code. Please make sure you spelled it right." for each of those keys.
What's going on?
