Done I crash when I try to join the server after crashing when opening a reward bag.

If you go back a couple strings in the crash log it goes to:

com.mumfrey.liteloader.core

which makes me think it's an addon to the packs? If you disable tabbychat and the voxel add-ons it might clear itself up. I would delete those folders (and the liteloader core) and uncheck them when it asks (and probably click hard force update) and see if that works? A shot in the dark but liteloader.core a few classes back makes me think it's one of those.[DOUBLEPOST=1401495527,1401495279][/DOUBLEPOST]Another class to note in the crash log:

net.minecraft.util.ChatMessageComponent

again makes me think tabbychat. I know tabbychat settings get saved somewhere else. if you had a tabbychat filter that is conflicting, that wouldn't get deleted with a full re-install of the pack.[DOUBLEPOST=1401495742][/DOUBLEPOST]Make sure to delete Minecraft > liteconfig folder;

Minecraft > config > Tabbychat folder

 

this also happens to me when i start AS with the normal FTB Launcher when i try to play AS.
And tabbychat and the liteloader are not in the regular AS-pack right?
I just spent over an hour talking to the guys in #FTB but they also couldn't help me.
They said its an network issue that prevents my minecraft in general (not just FTB) to connect to the DNS properly.. whatever that means.
We tried everything from disabling my firewall+anti virus, reinstaling FTB in a different location, adding exceptions everywhere.
But nothing helped.
We figured out that the crash only happens after i started any modpack the second time after rebooting my computer....
Like when i start it the first time after rebooting it works and i can connect / disconnect as often was i want.
But when i close the game and relaunch it it doesnt work anymore... Noone knows whats the problem with that.[DOUBLEPOST=1401498221,1401497701][/DOUBLEPOST]They just looked at my launcher log and it even outputs an error before i even selected a modpack and launched it.
[0226] [INFO] LaunchFrameHelpers.printInfo FTBLaunch starting up (versio - Pastebin.com
So the Problem is on my side not on yours.

 

Well that sucks, I really was trying to figure it out!

Hate when people can't play what they want. I think it's safe to say that this is yet another reason Java should be avoided like the plague when making a full-scale game.

Have you tried port-forwarding yet?

 

Yea we also tried that.^^ Like i said i was talking to three guys for atleast an hour and we tried all kinds of stuff.

 

i just updated to java-update 60 and that worked for now. I'm not sure if that fixed the problem or if its just an coincidence now.

 

That works though^^ But i just crashed again like two minutes ago.

EDIT:
I just realized that this creeperrepo.net is host for downloading FTB Modpacks etc. In the normal FTB Launcher i can change which server i want my Launcher to download from. I thought i could try changing to a different server and see if that fixes it? But i cant find this option in the MyM Launcher.
