Can not upgrade from 1.5.2 to 1.6.2

Upon running new 1.6.2. launcher play button is inactive. I do not need registration since I've already got Mojang account.
I've tried empting .minecraft folder and Java update. It haven't fixed issue. Also I tried to disable antiviris and firewall- no change. Hosts file does not have any lines with minecraft or s3.. Please see attached logs.
