Your modpack.jar is named modpack.jar.jar. Fix that. Also, don't unzip it or add to or remove anything from it. Just rename the forge universal jar to modpack.jar. Your pack only has NEI, and it has a (1) at the end of the file name. Fix that. After you get forge working, start adding mods, but test it after adding one or two mods at a time.

Sorry for the quad post. Can't edit them either. A funny thing must have happened on the way to the forum today. Sorry for the quad post. Can't edit them either. A funny thing must have happened on the way to the forum today.

Use pastebin and post the crashlog and a link to your modpack. Attachments don't work.

No such animal in this version. Look for the redstone furnace.

Do you mean redstone furnace? I've never done tekkit lite or classic, but there's nothing in this tekkit called an iron furnace.

Tesseracts really are the solution for moving energy / items / fluids to far away places and other dimensions. Automate their production if you are going to need a bunch. Build and use the AE MAC to mass produce them once you have the raw materials.

Looks like a 1.6.4 modpack with java 8. Add in Lexmanos java legacy fixer.

Add Lexmanos java legacy fixer.

MFFS sponge mode can help. It can quarry too.

Try updating all of TE to the latest versions, especially COFH core. Post your modpack API url too.

If you've got big ender pearl needs, look into an MFR enderman farm.

Allocate 3gb of ram in the launcher settings (the cog wheel button)

Been awhile since I've done tekkt 1.6.4, if it has enderio dimenensial transceivers, you can try those.

Best bet is to pick 1.7.10 as your base. Download the latest version of Forge for 1.7.10. Get Forge working with no mods. Then download the 1.7.10 version of the mods you like from the authors website(s) and read the author's instructions. Add them in, one at a time, and launch forge. It it works, add another, if not, fix the issue. Plowman made a great guide for this, I will see if I can find the link.

I'll download your pack later to see more, but a glance it looks like you are running an old version of forge for 1.7.2, and have a mix of mods that are for 1.6.4, 1.7.2, 1.7.10, and 1.8. What version are you making the modpack for?

Pastebin a crashlog.

How much ram do you have and how much are you allocating to the launcher?

Need a crashlog and modpack API url.

We do, and you're whitelisted.

Learn the Tinkers Constuct mod. The manuals for it are even provided in-game.

In the mods\1.7.10 folder

Do you have the most recent aotbt server download? This one is missing the Lexmanos legacy java fixer mod.
