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

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.
