Game no longer accepting my validation code, even if it's correct

[Platysynthesis]

Ever since the Maniaplanet 4 update arrived, the game-- for some reason-- forgot my validation code. When I was selecting a car mod I downloaded from Maniapark, it told me that I was not able to buy it until I entered my validation code again.

Because that I forgot my original one, I went to Steam to grab my Trackmania Stadium's CD key and went to the player page to generate a new one. Using the new validation code, I tried entering that in but it just said that it was not correct. This method worked before so I don't really understand why not now.

Can someone please help??

Nevermind, I had it fixed. Apparently, I needed to go to the NEW player page since I was using my old one. Generated a new key there and now it worked.
