Vault not working

[Nuggets75]

Hi, since the last update (the switch to the bigger server) I can´t download any Maps or Mods, it says something like "Cannot download this Map, because it was not found or is broken". I tried a new installation and the repair option, but nothing worked, so did I do something wrong or does this need to be patched? (Another guy downloaded the same map I couldn´t so its not the map).
