Collectible Card Game Headquarters

So my old computer this happened. When i would load up the program when it gets to loading the quest data it gave me this error. I just stopped playing forge because i could not figure it out.
I eventually got a new computer (not related) and this same situation came up. I tried deleting quest data. I even tried deleting all of the RES folder and reinstalling the program...still the same error. I am on a Macbook Pro btw.
If any of you have any insight i would love to hear it. thanks
