Somehow, after upgrading my laptop to Windows 8, my League of Legends client tends to crash while the game is loading (after champion selection).
I have to manually kill the client in Task Manager, re-log into the client, and launch the match again. This occurs on an average of 5-20 times in a single session before I could get into the match.
When I do get into a match, the in-game screen is bugged: I can't see my champion, stats, other players/enemies..nothing.
I also find that after a crash, the game takes a long time to spawn the champion in the match. The progress goes from 0% - 35% then stops, and then it starts moving about 1% every 2-3 minutes.
Can anyone tell me why this is happening?
