I had just joined a game and lost lp for it ?

I just joined a game and it just stopped. Everything else in the client was working i was able to talk to people still but it just took me into Que and froze. I was one game away from promos. NO it was not my internet i know for sure , and NO it was not my PC because i was able to do other things on it but i think it was just the client. If you people do not see a link let me know ill show you .
