A critical error has occurred and the proces must be terminated.

Although I am able to log into the game and see my client, I am unable to join a game of any type. I realized this when trying to join my first PVP SR game of the day and instead of showing the loading screen after selecting my champ (along with everyone else in the pre-game lobby) successfully, I received a "critical error" message once the game started to try to load the actual match. I have done the types of memory dump reports that the screen recommends and have that data, but no one to send this information to and still no way to join a game of any type. ** I cannot even play a game in the training tool. ** This issue is happening on both of my accounts even after powering off and back on my computer and closing unnecessary programs. It is happening on all maps it appears as well, since the exact same issue occurs when I create a custom game on Twisted Treeline.

So again: I can create the lobby, select my champ and spells, but as soon as the screen changes and the game tries to do the actual loading of the current match, this "critical error" occurs. Please help!!!!
