[CLIENT] Can't load in past 10% on game then crash!

I can search for a game, accept Q, and get past champ select all fine. Then loading into game the first time gets to 90% and then client closes and tells me to reconnect to which I try over and over again to no avail! Just "reconnect" over and over again! I've lost a rank game because of this reason! Please send help! [sg-janna]

            - This is the 2nd time in 24 hours and I do **NOT** use Avast Anti-Virus.*[sg-miss-fortune]*
