Title Modded Minecraft Launcher crashes instantly

Launcher Type Curse App

Modpack All The Mods Expert

Modpack version 1.0.22

Have you modified the pack? No

Link to log file http://pastebin.com/vqvCLEtF

Details of the issue Not sure what is going on here. I was able to load the pack and play for a bit, then I decided to install optifine and dynamic Lighting. I then started to receive this error every time I would launch the pack. I uninstalled the mods and still had the problem. Here is a list of the things I have tried in the last hour of messing with it:
Uninstall/reinstall Java 64 bit
uninstall/reinstall the curse app
uninstall/reinstall the modpack
tried a different modpack (same problem)
restarted several times
rolled back my graphic drivers (and updated them)
Needless to say Im stumped. Any help would be greatly appriciated!

Same Problem here, Do you have a fix yet? Cuz On no launcher no modpack workt. But vanilla workt fine :(
 
If this is the new Mojang launcher then you should be able to go into Curse settings > Minecraft and change the Minecraft launcher from 'native' to 'jar' this should get things working again.

Support for the new launcher was added to Curses alpha branch yesterday so a more long term fix is definitely in the works.
 
Nope, It doesn't work :( it also doesn't work on FTB launcher,
