1. Okay, what I want you to do first is power cycle your internet (Which would mean unplugging everything for about 5 minutes, and then plugging everything back in)

2. And once that is done, try launching it again.

3. Now, if that does not work, contact your ISP and tell them you want to forward the following ports: TCP (54992 - 54994, 55006 - 55007, 55021 - 55040) (30 ports.... ugh)

4. Go away, we don't like you.
