Hey, I started up my modded cleint after shoving a bunch of mods in the folder, fully expecting this to happen, and it did. Here's the crash report (I don't know how to spoiler)

Also, a picture of my mods folder:

Bump

Have latest 1.6.4 version forge. Will install legacy java fixer.

Installed java fixer and updated forge. Now the launcher says, after being launched:

Forge mod loader has found a problem with your minecraft installation. The mods and versions listed below could not be found:

Forge: minimum version required 9.11.1.953



this confuses me because I have forge version 9.11.1.965

Above issue fixed. New error. Yay.

Decided "**** Ic2. Tropicraft instead. Let's see if it works. If not, will try to fix IC2
Decided "**** ic2. Added tropicraft instead. Pack works now.

I wonder where people get the new one. Anyways, I found the right one and the universe decided to stop screwing me over, everything works now. Also, added flans with 4 packs and tropicraft, no issues. Changing thread title to resolved.
