I need a little help. I'm trying to play some RPG maps on Stadium, but even after I add the Pack to an empty station and try to play maps through it, I receive an error that there are a lot of GBX files missing.
Also, if I try to enter any RPG online server, I receive the message that my version is not up to date.
Tried with the Steam Version and the ManiaPlanet version, and both have the same result.
I only have Trackmania Stadium, maybe I need another one as well?
When I try to play Eleum Londor (https://tm.mania-exchange.com/tracks/view/129589) for example, I get the message that I'm missing this:

If I try to play it through the TM Stadium or through the title pack, the result is the same. Any help is appreciated!
