I just got a new laptop, brand new, fresh out of the box. I've installed Technic Launcher on various PC machines in the past and also played Attack of the B-Team with no problems. My problem that I have is that on my new laptop it does not want to launch Attack of the B-Team. Technic Launcher runs good. And also other Mod Pack (e.g. HEXXIT) run perfectly with no problems. Just when I press "PLAY" on Attack of the B-Team, i'll load like normal, the launcher with close like normal, but then Technic Launcher with open again. And that's it. I dont get the Mojang screen or nothing.
My java 25 x64 is up to date, i have changed memory from 1GB to 2GB, i also have selected "Always use beta launcher builds", and i also deleted the mod pack and re-downloaded it various times.
This is the error i get...
