I recently got back into TrackMania having not played it in a couple of years. And I decided to play some of the maps that I downloaded and played for Stadium and for RPG. But for some reason no matter what map I play get a 404 error in which the map data, such as custom skins and music, fail to download. So the maps are all bland, and especially the RPG maps the textures that define the title pack are all missing.

I checked this site already and downloaded updated versions of each map, and I figured out myself that the install and play button will always cause an error 500 that softlocks the game. Even on a new download and install not every data downloads. For some maps the skins download, but for all the music always fails. I play the game mainly through Steam and I tried the standalone ManiaPlanet installation to see if it would be any different, but I get the same problems.

Error message example:
Unable to download data: Skins\Stadium\CircuitScreen\ssl.jpg
Cannot connect to the server (404)
