Windows .exe Launcher don't run 1.6 packs

[Poyzon]

Windows 8.1, 64-bit
Java 7 Update 51 (64-bit)
Launcher version 1.3.4
Pc total RAM 4 gb (3 usable)
Allocated RAM 2gb
I have gone through the troubleshooting guide.


Now the Launcher opens just fine and i can play for example in unleashed server w/o problems, but when i try to launch 1.6 modpacks i get errors that say "[WARNING] [ForgeModLoader] The coremod codechicken.core.launch.DepLoader does not have a MCVersion annotation, it may cause issues with this version of Minecraft" then the launcher closes itself. I used to ba able to run the game without any problem, but for some reason its not working properly anymore since yesterday.

I already tried force update serveral of the 1.6 ftb modpacks, made clean installs of java 32/64 bits, since ive to have 32 bit for my browser and 64 for minecraft.
Also tried complete delete the install folder and the .minecraft folder (vanilla 1.6/1.7 works perfectly with the vanilla launcher)

There is a pastebin of my log:

That error is normal and is not causing a problem. I don't see an error in your log. If it is crashing then make sure that you tick 'reopen launcher after exiting minecraft' in the options. This will cause the launcher to reopen in the event of a crash then you will be able to post the log.
