I keep getting dc'ed from game.

This has only happened once before, when i left my client idle for over 2 hours, but this time i just turned it on and tried to join a normal blind pick. The first signs of the problem were when i god dc'ed from chat. That fixed itself automatically. But after that when the game started i got dissconnected every 10 seconds and reconnected in 5~8 seconds. The program told me it was to do with my connection, but my internet is perfectly stable with no problems.

Pls fix soon rito. With love.
