I have the same problem at the moment, i live in Romania where we have the best internet in the world i believe. Never had this kind of isues untill yesterday. After 5-6 hours my last file decided to download himself, now, after i woke up, for like 4 hours i`m trying to get into the launcher. This is what i get. I`m starting to regret that i bought this game despite i like it.
