Hi, I downloaded the new 1.6.44 launcher today, and my 1.7.2 forge and mod profiles won't load the game. I tried running 1.8.8 and thats fine, but the forge profile simply will not open the game. It doesn't crash, but the latest log is below.

Can someone please help with this or at least show me where to download the old launcher? Thanks!
