[Error] Random irrelevant error

[Charmeleon4661]

I am creating a game in PK. Essentials. I was testing the game when, out of nowhere, this error occurred.
-----------------------------------------------------------------------------------
Script 'PokeBattle_Trainer' line 197: NameError occurred.

uninitialized constant PokeBattle_Trainer::PBSpecies
-----------------------------------------------------------------------------------
This is a script error, of course. I had not been doing anything at all relevant to that script and in fact I hardly ever modify the scripts at all. The most recent things I had been doing were:
- Removing a Trainer I had created by accident from the trainers.pbs file
- Adding a line in an event that enabled Mystery Gifts
I really don't know what the problem is. If anyone needs more info, I can provide. Thanks for any help!

From line 194 to 207 in PokeBattle_Trainer is this your code?

def pokedexSeen(region=-1)   # Number of Pokémon seen
    ret=0
    if region==-1
      for i in 0..PBSpecies.maxValue
        ret+=1 if @seen[i]
      end
    else
      regionlist=pbAllRegionalSpecies(region)
      for i in regionlist
        ret+=1 if @seen[i]
      end
    end
    return ret
  end

Yup, it is. I'll add a screenshot of the code to the post.
EDIT: Nevermind for some reason the image I uploaded went to really low-res.

Good news! I tried starting the game from RPG maker and then starting it again from the .exe file and now it is working fine! Not sure if that was actually what fixed it, but if you are having this error, maybe that will work.

So I know there's a rule about not reviving dead posts, but I'm having the exact same problem, I've been searching for an eternity and I can't seem to fix the problem no matter what I do (yes, I tried to start the game from RPG Maker (playtest), and then again from the .exe file, but nothing seems to be working). I tried to cancel out that specific line in the script editor, but that just started a whole chain reaction of problems that wasn't there before, so I un-canceled it again, but it's still the only problem preventing my game from starting...
