Okay, I got it to work, and what I think most poeple are doing.
Like most, I redownloaded PokeMMO earlier, leaving me to delete the .txt's within the PokeMMO Calculator folder.
When I downloaded the latest version, they weren't included, leaving the program to not know what it is reading.
I would recommend adding the .txt files to the download, along with a new "PokeMMO Calculator" folder if you can, to prevent confusion.
I feel stupid. lol
It sometimes takes a few re-scans, but it works.
