Thanks everyone for the long explanations, I bought it on Uplay, and activated it in my main account.
It asked nothing about where I want to active the title, just launched ManiaPlanet from Uplay once, logged in to my account, and bam it was there.

Great thing to know!

Thanks for the information! And sorry for complicating this thing so much, but does it work the same way if I buy it on Uplay?

Thanks for the reply, maybe I'll give it a go. I'll give feedback here if I could active it in my main account or not.
Actually if it doesn't work, I might just get in contact with the ManiaPlanet admins and ask them to migrate the game (my activation key) if it's possible. Who knows.

Hi, I bought the three TrackMania2 environments (Stadium, Canyon, Valley) from the official webpage some years ago, and I activated the codes in my ManiaPlanet account. Now if I buy the Lagoon from Steam, and not from the official page, will I be able to activate it in the same ManiaPlanet account, ...

Nice mod! I looks pretty good, but where should I install this zip? Or I have to extract it somewhere? Please help, I want to try it out!
Thx: Cheatman
