Client Disconnect before Loading Screen.

I am aware that there might be a thread of this alredy, believe me I looked and none of them fixed my issue.

Earlier I ran CCleaner on my PC, no biggy usually. I am not saying it is the cause, I am saying CCleaner is a plausible element in the madness.

I joined an ARAM game approx. 24 minutes ago. after a few minutes of attempting to reconnect and it allegedly doing so but refusing to show me anywhere- other than in the task manager- that League was even running. I decided to hop on my laptop while my desktop reinstalled it (Which it is now going through and applying the patches.) But it was too late, I recieved my first report message, ever. That dishearted me.

But I would like to start this thread in hopes to find a solution, and maybe discuss with other tech savvy folks about why it refused to operate properly.

Does anyone have any ideas?

I might add that I put an exclusion in CCleaner for League.
