Chat won't load in ranked team select.

Whenever I play a game the chat wont connect during team builder (It's blank and never even says who joined the room). Is there anything that can be done about this. Obviously this really hurts my team and I can't continue to play ranked until this is fixed. :/

Note: I restarted my computer (which is a nice one and new) and I even deleted and re-installed the game. Same problem though.
