I have 16GB of RAM

So I recently downloaded the Technic Launcher to play MoonQuest with some friends. However, I launch the pack fine, and if it is the first time launching the pack (yes, it happens with all packs) then I can create a new world fine. I play for about a minute, the my framerate drops dead and Minecraft stops responding. I close, restart the launcher, then load up that same world. Stuck at "Downloading Terrain". I'll create a new world, and the same thing happens: stuck at "Downloading Terrain". I have tried to completely delete the installer, reinstall it, and allocate more RAM. I have no idea what is going on. Someone please help?
