Bug splat, lolclient.exe has stopped working, and now a 30 minute ban

I had just selected Fiddle, and the team capt picked renekton, so I clicked he summoner icon to familiarize myself with his abilities.

I hit the Abilities tab, then bam, the bugsplat, log back in and I get a 30 minute ban.

Please fix this.

I've reported numerous numerous numerous times your client has an issue, crashes and then blames me.
