I have this weird problem. Already asked it on the minecraft forums, but I think it might be problem with forge, cause it actually affects few different mods (ICMB, UE and buildcraft). Here's the quote from minecraftforums.net:

 

Ok, I cannot fix the issue. Here's what happened.

Today while I was trying to start minecraft, my PC suddenly bluescreened. Since then, I cannot run minecraft. It just gives me black screen with no crash report (but I have a FML log). I didn't change anything since the last time I played it, nor did I update any mods. When I removed all the mods, it all works fine.

I tried redownloading minecraft and reinstalling forge and optifine, but still nothing. Then I started removing mods in order to find which one is causing the problem. When I removed ICBM, minecraft finally threw a crash report at me. It looks like the mods that are causing trouble are ICBM, Universal Electricity and buildcraft.

 

I thought what happened was that when my pc crashed, it caused some issues in the mod files. But redownloading them didn't help.

 

Anyway, here's what I've found in the FML log file:

Caused by: java.lang.RuntimeException: unknown character

 

I've posted this in Calclavia's ICMB topic and he said that's a really weird error and there might be a problem with Java. Reinstalling it didn't help though. Also, tried running without Optifine and still nothing.

I was thinking that it might be a problem with some forge files, where it saves mod data or something? Maybe those files got corrupted when my PC crashed. Don't know how to fix it anyway. I hope someone can help, cause I've literally spent three hours trying to fix this

Make sur you save your config as UTF-8 when you edit it, Forge should support anything in the UTF family, but some reason it's not.

Or, you screwqed up your icbm config file and need to start new.

The thing is, I didn't change ANYTHING at all. But I'll check the config files, maybe they got messed up when my PC crashed.

 

EDIT:

Ok, found the issue. Looks like config files really got corrupted, they were basically full of NULLs. Reconfigured everything and now all works fine. Thank you
