alexjuuhh: Not my fault, looks like some side effect of class loading from transformers. The actual issue is missing from the log, try running with -Dlegacy.debugClassLoading=true to get more information.
Ran it with that parameter. How about now? http://pastebin.com/QDFNaDy3
I'm having an issue in the latest release of Resonant Rise 3 concerning FastCraft (and AppleCore), where the client crashes with both enabled. I already posted a report on the Resonant Rise forums but that didn't help much. What they did tell me is this:
Well, the error shows that AppleCore fails to find some basic Minecraft class to do runtime modifications.
I'd say this is caused by FastCraft applying it's changes to that class that make it different from what
AppleCore expects.
Here is a pastebin of the ATLauncher log: http://pastebin.com/5TfYfFnW
When I remove FastCraft from the pack, the client does load, which leads me to believe that it's a FastCraft issue, not an AppleCore issue But I could be wrong, of course.
The mods in the original post are the only mods I've installed. Nothing else. Oh and Single Player Commands.
What class-file would I be missing?

Never mind, I fixed it. Had to install Audiomod and GUI API and then it worked. 
Hey, I'm new to IndustrialCraft. I installed ModLoader, Mineforge, TooManyItems and ReiMinimap to Minecraft.
But when I try and start Minecraft, I get the following error after the Mojang screen:
Mods loaded: 2
ModLoader Beta 1.8.1
mod_IC2 v1.15
Minecraft has crashed!
----------------------
Minecraft has stopped running because it encountered a problem.
If you wish to report this, please copy this entire text and email it to support@mojang.com.

Could someone help? thanks!
