Maybe look into your "\Documents\ManiaPlanet\Packs" folder, remove the RPG title pack file and redownload it. That's the only thing I can still think of. You are the only person we know of that encountered this issue, so it very likely has something to do with your setup. gl

How do I get the mod(s)?

Go into the main menu, then click on "Tracks" in the lower right corner, then on "Mods"

Hm, I did redownloaded, but still the same happens.... But the file I download from the provided link is only 92MB, can that be right? Just seems small provided it contains 3000 objects....

Yes, the file is only 92mb in size...that's normal. The titlepack itself does not contain any textures, they are added via mods which are themselves ~100mb in size. That's part of the reason why the download is so small.
The only thing that you can try now is a complete ManiaPlanet reinstallation, dunno if that helps though. Maybe try your luck with a ManiaPlanet forum post asking for help before that though.

Oh, ok... Tnx a lot HawkGer ! Reinstalling for me is a really HUGE task, because I have to bring my computer to the city in order to find a faster internet connection... So think I try a post in Maniaplanet forum first......

Problem solved ! I transferred the pack to programdata, as advised in ManiaPlanet forum, tried again, but still the same. Then it stroke me, maybe I have to be online for it to work? So I connected, was lucky that i could, coz usually my connection are just to slow... Then I clicked again, and it SEEMED still not to work, but this time I left for a while, and when I came back, IT WAS THERE ! Probably I just did not waited long enough before.... OR, have to be connected for to load new titles... Now I will just use my download manager to download those awesome mod during nigh time... After a few nights I probably will have it downloaded....

Cred to you guys. Awesome work
