I am having some issues with mods that use .jar files (here forestry and IC2) instead of .zip files. System information listed at bottom of post in spoiler tag. All mod installations were done manually (not using multiMC or anything like that). I first installed forge (yes, I deleted the META file) and ran minecraft, then installed the chickenbones mods and verified they were working. When I placed the industrialcraft jar file into my mods folder, and ran Mincraft. The program got stuck on the Mojang screen (after letting it run for ~5 minutes, I figured it wasn't going to run). None of my log folders show any errors. I then removed the IC2 file and tried with Thaumcraft. Minecraft launched successfully, and using NEI I verified that the mod was working. After I installed all of the other working mods, I again verified using NEI that all mods were installed and running. As soon as I placed either the IC2 or Forestry files into the mod folder (note that these are the only 2 mods I have installed that use jar files instead of zip files) I again had the game stick on the Mojang screen. My computer didn't freeze up or anything like that, the game just didn't seem to launch. Again, my log folders didn't show any errors, and I will post those beneath my system info in case there's something I missed (I am by no means a code expert). Thanks!!
System and Mod Info
Log Files
EDIT: Upon reviewing my post, I found an error that I missed the first time I reviewed the files. Forestry appears to have some error, but just removing forestry doesn't solve the problem and yields another set of log files with no errors.
