Operating System, bit type: Windows 7, 64-bit
Java version/update, bit type: Java 7 Update 51, 64-bit
Launcher version: 1.3.3
Completed the troubleshooting guide (y/n): Yes
Console log, pastebin.com link: console output, FTBLauncherLog.txt, MinecraftLog.txt
Description of the problem:

Every time I try to launch any pack running on Minecraft 1.5 or older using the Play Offline feature it does not launch. The launcher and the Play Offline window simply remain open. The problem occurs with any pack that doesn't use Minecraft 1.6, the linked logs are for a clean FTB Unhinged 1.1.0. Launching the pack with an internet connection works fine, as do 1.6 packs online or offline. Both the exe and jar launcher have the same problem.

PS:
Sorry for bumping this, but the issue got resolved in the launcher version 1.3.4, everything works fine on that version.
