Can't watch my replays, my Imac keep crashing and it tells me Bugsplat, error occured.

I can't watch my replays from match history, after 3-4 secondes, it crash and I'm back to the client LOL. The client is working, but I can't rewatch my games. I tried to uninstall, reinstall, not working. Rito fix ur game before promoting some mental illness or adding new content to the game!
