Can't run launcher offline

[Ilgam]

Please help me guys. I go on vacation next week and I will not be able to play online. So I need to be able launch FTB without internet connection. I heard, that there is an "offline mode" in the launcher, but my problem is that I can not run the launcher offline. I open "FTB_Launcher.exe", then it runs a console and that's it. Normally the launcher appears after console, but when I launch it offline, there is only a console with a crap load of red text in it. I also tried to launch FTB on MultiMC, but it didn't work either. Need help, it's very important for me guys. Sorry for my broken English, I hope you understood my problem.

Here is a link with red text form console: http://pastebin.com/0iGDmYwA
I also did an online launch. It works well and all my stuff is up to date.

As far as I know you can't run the FTB launcher in offline mode. But you can with MultiMC.
