Error 0xc0000005 - Nothing works anymore??

I have done all that support has suggested on the issues.. Uninstalled, reinstalled 4 times.. deleting the old directory even, trying it on a different drive even.

Everything works until I get into the game.. Champion select works.. No problem, pick my skin, pick my 2 powers, all my selections.. timer goes down to zero. game kicks out.. then I get an error screen Application process error 0xc0000005 . I try to reconnect when I hit the button and it does it over and over again.

No idea what the issue is after all the issues yesterday. Any suggestions would be greatly appreciated.

I have spent close to 90-100 bucks in the last few days buying those stupid boxes, skins, and champs for friends and myself.. and now I can not play for some reason.

I don't want to quit playing but its hard enough with all the bugs and stuff lately and now this so I can't even play? Is there any way to request a refund if I can't get the game fixed and play at all?

Thanks
