League of Legends doesn't install in Ubuntu 14.04 - bugsplat

After I updated to the new patch (6.19) in league of legends (I use Ubuntu 14.04) when I logged in, the game immediately crashed (bugsplat) without me doing anything. I couldn't even make it to champion selection. So, I decided to uninstall and re-install the game but now the installer crashes too (bugsplat) and I can't install it. It always happens when it's about 42-43% done at the second step and I have no idea how to fix this so for the past week I can't play the game. Your help would be really appreciated! Thanks in advance
