I got past the champ select for TT on the live server and when it goes to the loading screen a window popups up saying:

"Client/server version mismatch"

Client Version 1.0.0.152 [PUBLIC]
Server Version 1.0.0.151 [PUBLIC]

Any help on this?

EDIT: Ran as Admin and it loaded fine. What could have caused this problem?

EDIT 2: Someone declined the game I tried joining (after a couple successful connections to games) and it stayed at that screen, where you choose to decline or accept. It showed I was out of the queue and then suddenly kicks me to a game lobby and says I was locked in and the game was beginning. It never started and I had to exit the client to fix the problem.
