I'm using the latest recommended version for minecraft 1.7.2 and it doesn't matter what I have tried I can't get the client to start and always get this error.(before it I was getting an --accessToken error but I fixed it then this showed up).

I needed 1.7.2 so I could finish what I was working on and get a release out for it but as soon as I updated to 1.7.10 it started working.

Well, I have the same problem, and my girlfriend wants to play minecraft with me but she uses 1.7.2 and has 63 mods installed and doesn't want to update to 1.7.10.

 

So yes 1.7.2 DOES matter to some people. Please give an actual solution.
