So basically I have quite a large modpack, 160 mods or so. However, recently I had to re-install my OS or rather, downgrade from Windows 8.1 64 bit to Windows 7 Ultimate 64 bit (Not much of a downgrade in my opinion )
Anyway, after the downgrade my modpack stopped working (meaning it was working previously.) Its not anything stupid like me not re-installing java or anything because I did that from my external hard drive before I even re-installed the wifi drivers
Heres the modpack link: http://www.technicpack.net/api/modpack/insertnamehere
Heres my error log: http://pastebin.com/upn28HMj
Thanks for the help,
