100% FTJ games?

[PaintedDots]

I get failed to join game 100% of the time with all characters on D2X2, including creating a brand new character. 100% fresh install of 1.13d (just did a complete refresh install), just deleted and downloaded brand new C3P0, using compatability mode to Windows 8 (because it doesn't inject otherwise) and running as admin. Any ideas what the issue could be?

Edit: both on Ladder and Pro.
