Crash report on EUW BUGSPLAT

Now my problem is that I keep getting crashed out of the game, then I get BugSplat Error report which tells me to send Error report with those additional files

What to do? I don't get it I searched all forums for such a problem but nothing!! and for some reason when I tried to play at EUNE it actually didn't give me that problem it only seems to be happening at EUW, and I don't want to play EUNE.
