Help with crash report

[bkcarlito]

For some reason Unleashed is crashing after I launch the game. First it wouldn't even download the modpack but got that fixed. It worked 1 or 2 times after I tried a couple solutions and now it won't go to the menu screen in minecraft, just crashes.
Here is the log from the console: http://pastebin.com/sn95GSAN

Here is the actual crash report: http://pastebin.com/7Q56R4XS

If I was reading the crash report right it is saying that there is an issue with the Config file for CodeChicken. If it is the problem then I don't know how to fix it. I'm still trying to learn how to read a crash report and how to fix it. So far I can only semi figure out the problem.
Can anyone tell me how to fix this issue, please?
Thank you for taking the time to read this and hopefully help me.

In my experience helping on these forums this error is caused by an over zealous Anti-Virus, AV, program. Try adding the mod pack folder to the exceptions (exclusion) list in your AV.

I disabled my AV and still shows same crash report.

I disabled my AV and still shows same crash report.

Depending om what av you have it may not like being disabled. Try what lavarthan suggested.
