Okay, so, I solved my problem, and maybe other people might be having the same one. I was using the mod Plunder Rummage in my modpack, which apparently needs the creator's permission to be included, because if you don't have his permission, it's actually rigged to not let the game open. Anyone else who can't get a modpack to open, if you're including this mod, either delete it or get his permission. I didn't give a shit about modder permissions because the pack I am making is for me and one or two other people to play, not to be posted publicly, but that's a discussion for another thread (that I won't be starting because I don't care). Hope this will help anyone else!

Having the same exact problem, but only with my custom modpack, I can load others just fine. Might be related.

I've been trying to make a modpack for 1.6.4, and just downloading the latest forge universal (for 1.6.4 of course) and renaming it modpack.jar hasn't been working. So I used the 1.6.4 one listed here, and my modpack loads up and then tells me that "Forge minimum version required is 9.11.1.952" and then... it goes to the title screen with no problem. Until I close the game and launch it again, at which point it gets stuck on the "Minimum version required is..." screen. Obviously, one or more of my mods needs the newer Forge version. But just downloading the Forge universal file and renaming it isn't working, I have never seen the title screen with it. It'll just linger on the Mojang screen and then close back to the Technic launcher. What did you do to these that makes them work right? I followed the instructions over and over to make sure I got it right. Downloaded the Forge jar and renamed it, then made folders for my mods and configs, and ZIPed it, hosted it on dropbox, downloaded it via Technic... it's driving me crazy. How did you make these files? I'm not gonna ask you to make ones for the new version of Forge, I want to be able to do it myself.

Sorry about that. And thanks, I'll look into this.

Bump

Trying to make a modpack just for me and my girlfriend to play on. She has a Mac, I have a PC. I uploaded everything via dropbox and technic and when I download it, it runs fine for me. She downloads the same modpack and gets a black screen when she tries to run it. I had a few of my other friends try it, and they can run it with success. I'm going crazy trying to figure out why it won't work for her. Any ideas? Maybe someone who plays on Mac can download it and see if it runs for them, so we can determine if the problem is her not being on PC? Any help is appreciated. Thanks guys.
