Entry Point Not Found

Normal day. Decided to play ranked matches. However, when the character select lobby launched, I got sent straight to the "reconnect" menu. When i tried pressing any other button (like report a bug, or anything on the friends list bar). I got an "Entry Point Not Found" message. When I did try to reconnect, nothing happened... I closed the game, but when I try to open in... "Entry Point Not Found." Now I can't open the game, probably will have to reinstall it, and have some dodging penalty against me... facepalm
