Maniaplanet Forum

When I play offline, it said Unable to load Trackmania Canyon, when I click ok, Could not install or update the title files, Click ok again, this title isn't playable, that so boring, please fix that issue

If you are able to play "online" there is no reason why you should not be able to play it offline, normally.

Are you mixing up offline with a local account perhaps?

Because you need to start Maniaplanet with the same account on which Canyon was activated.
Another pure local account will not allow to play.

Did you purchase a valid key for it?

Or are you only playing in the channels, which are free?
