So I think that on my computer it is because of a windows update, because I wiped my computer completely and then reinstalled technic and everything worked, but then I got the windows update and it stopped working again.

Also I tried uninstalling everything and deleting every file related to minecraft, technic, or voltz (the only mod I play) and then redownloading it and it still doesn't work

Launcher Version: 242 Operating System: Windows 8 Surface Pro Java Version: 1.7.0_21 Antivirus Program: Description of Problem: I select a modpack (any modpack) and click Launch and then the launcher closes and the FML thing opens up, and then it closes itself and does nothing else. I tried using the console while the launcher loaded, and the last thing the console said before closing itself was "Accesor Unsafe". This started after I installed the latest Windows update. I uninstalled the update but that didn't help. I have tried clearing the cache and it didn't help either. I also installed a Java update around the same time and I think also an update for the launcher but I'm not sure. Also, I tried using the .jar launcher and when it got to the minecraft update part it said "Update Failed" and stopped.

I think I might be having the same problem... I installed the latest windows update and now when I try to open any of the games from the launcher, it loads all the mods and then the console says "Accessor Unsafe" and the game crashes...
