Are you sure what you installing are Jar mods? Thanks to Forge there really aren't many that are. Do you have a list of the mods you're trying to add?

Pretty much the only things in javmod section should be
Forge
Optifine
NEI config thing
Volex(votex?) menu config thing
Everything else lives in Mods

The 3 mods that are there are the 2 that come with FTB and Optifine. I've tried them one at a time and they still crash the game. Any ideas?

I'm afraid I think we're going to need a bit more information to go on:-

FTB Launcher version (if this isn't the newest update update and try again):​

​

Modpack Name:​

​

OS Version:​

​

Java version:​

​

Detailed description of the issue / how can the issue be recreated:​

You've probably got the wrong optifine.

Mods I'm having an issue with is...

• OptiFine_1.5.1_HD_B2
• MinecraftForge
• liteloader

If I have them disabled the game does not crash on start up, when enabled it does crash after the FTB intro screen it goes to black screen and I cannot do anything.
I have Windows 7, Java Version 7 Update 17.
The full log from launch is here http://pastebin.com/CBLttyu3
I appreciated all the help.

Here's your problem. FTB is on 1.4.7 you need to download Optifine from the older versions section.

That's your problem.
FTB isn't updated to 1.5.1 yet.
You need optifine for 1.4.6

 

[Roosterr]

But even without Optifine it doesn't work, I have the same issue.

Probably putting the wrong version in broke everything else. I'd advise starting with a clean install of FTB and add the 1.4.7 version of Optifine.
