Problems With New Client

I was able to find a way yesterday to start up the client and away from the black screen. I then played a few games with a couple of friends and then instantly, after we won the game, my league crashed and wouldn't let me close it. I then shut off my computer and turned it back on.

Once I did this, I went straight back to trying to get league to start up again, but had a the client pull up, only to be greeted by a new L and a swirling blue circle to indicate it is loading.

I tried numerous things (Uninstalling/reinstalling, deleting certain files, etc.) and it didn't work. It got to the point I got a bit mad and deleted the bug splats on accident, but had them returned instantly. Now the new client won't even attempt to open. It loads the circle near my mouse but does nothing, hours on end.

Hopefully someone has had a problem similar to mine and knows of a solution.
