I had the same problem earlier! It's probably an error on my side... I did the whole 'set up a DMZ'-solution thing but I guess it didn't work... Sorry, hope you'll find someone else to take her (:
Sorry man, I'm getting an error code that apparently a lot of people get and I need to do something complicated with my router to fix it? Don't wait for me, haha, it'll probably take a while to figure this thing out.
