My campaign won't load properly

Hi to everyone, two days ago I was trying to put everyting in order to start my campaign but it seems that now it won't work. I've tried switching browsers and looking for trouble-creating plugins (Flashblock/Adblock plus & Pepper flash). I have joined other campaigns to check if they were working for me, and they are. I've asked one player to join the old campaign and he is also unable to join the old campaign. The name of the campaign is MLP: RiM, adventures in Ponyville.

Yes, thanks a lot for the fast and great attention! Fixed at the first try! Also, will it keep happening, if we accidentally reproduce the error? (I wouldn't do it on purpouse, of course, since I don't know how I did it)

One thing to do in the mean time. When you're copying content out of PDFs or Websites paste it into notepad first and then into roll20
