hey i am new to feed the beast and was wondering how to play this pack
		
		
	 
Hey, sorry for late response.
To begin with: original creator of this modpack - Fuuzect, no longer maintains the (current) modpack. Last time I made an update (which basicly just updated mods) was two years ago and since 1.7.10 is fairly outdated I long have forgotten about it. What's more, I'm not updating quests, adding new stuff etc. This was just to inform that this pack is exists, but is not maintained/updated.
And as for your question you have two options (well maybe three):
1) If you are using Twitch app, you can download the zip that's listed a bit above and import it there. Mods will be downloaded and you will be able to play it. Happens so Twitch app no longer supports Minecraft (?)
2) You can download it through the FTB Launcher with 3rd party pack code (no idea if that's still possible with new client), but then the pack will be older than the one I've updated.
3) Using MultiMC create instance and import zip (same one from 1st point), also you can download older version using 3rd party pack code, while creating new instance you would have to pick FTB Legacy launcher 3rd party packs.
As of now I'm kind of thinking to port this to 1.12.2 with all (or at least majority) of mods, quests and other stuff. 1.16.4 is out of the plans due to the nature of Minecrafts evolution and some of the mods being forgotten, no longer maintained. Worst case scenario, update 1.7.10 and maybe improve it a bit if that would give some sort of use for the pack.
