I'm having this problem: the launcher just stays at "Initializing." The times when it doesn't do that, I get the "Failed to download a required file," asking me to check if I'm connected to the Internet. And I obviously am, connected from home.

For a little more context: for reasons of time, I hadn't been able to play for the last month and a half, or so. And I could play perfectly, no problems whatsoever. I try now and stuff doesn't work.

Please, your help would be much appreciated.
