[1.7.2] Minecraft doesn't start after forge loads

[Balance]

There isn't a log because the launcher loads up fine, but minecraft never starts after. It works fine for 1.8.1 forge, but when I load up any of the 1.7.2 forge clients they do not work. I have reinstalled minecraft countless times and I have 0 mods in my mod folder. I deleted my minecraft folder, installed minecraft (runtime installs also) and loaded up a survival world with 1.7.2. Then I downloaded a 1.7.2 forge client, ran it and acquired the libraries, and started minecraft 1.7.2 forge. It loads very quickly, closes the launcher and then nothing happens after. Please help, hopefully its a quick fix.

Post your log.

Hi, minecraft doesn't give me a log. The launcher loads perfectly and then minecraft doesn't open after.

The launcher gives you a log, don't make me ask again it'll result in you being banned -.-

I'll make a gif/ video real quick. I'm literally here all day, sorry about any confusion. No need to threaten a ban, I'm just here to get some help

OMG STUPID POSTERS ANSWER MY PROBLEM

[Ugdhar]

Dude, for one thing, this version of MC is old and not supported anymore. You need to update if you want support here, I would say to at least 1.11.2.

Second, this thread is over 2 years old, almost 3. Make your own post, don't post in an ancient thread.

Third, you first posted 5 minutes ago. This is not a chat room, people are not always online. Posting 4 times in 5 minutes isn't going to get you help, it's going to get you in trouble with the moderators/admins.

 

Edit: Oh yeah, and calling people stupid, that's not going to get you much help.
