Math and Variables error

[Omanoctoa]

Hello!
I took a break from Minecraft and came back to create a new server. I've gone through my old MythicMobs many times over but cannot seem to figure out how to resolve this new error...

I have lots of Mythic Mobs but only one currently spawned in my world, however this error appears regardless if that mob is spawned. However, it appears to be impacted by the Error since none of it's particle skills work...

Does the following skill require Premium status to function?

Aura-ShieldParticles:
  Skills:
  - effect:particlesphere{particle=magicCrit;amount=80;radius=5;hs=.1;vs=.1;s=.001;y=5;}

Please help

Also, when I spawn my mob Console gets spammed with

...until I use Plugman to reload it.

Oh, side note, on a 1.14.4 server

You're on a non-premium version of the plugin, which is why you're seeing this error.

How would I install the Premium version manually? Due to restraints with my current Host, I have to manually add new files one by one. Would it be as simple as creating a new file called "MythicMobs-4.8.0" and copy the existing code into that file? It comes up garbled so I doubt it...any thoughts?
