Nope, no special characters, no "Ñ", check screens, all are in english and there is no weird folder names or Alien-scaly-fuzzy-martian-hard-trash-emo-grindcore, trihop, funk style structure.
Edit: At last find it out. It don´t allow spaces in the folder names...
So have Cataclysm Dark Days Ahead, changing it to CataclysmDarkDaysAhead that fix it.
That should be added in the op.
