So uh I'm having a weird issue where I can't play Unlimited at all. I've cleared Sumika and Meiya so I've unlocked it, but when I click "Start Unlimited" a message pops up asking me (I think) to insert the DVD or something for Unlimited, except nothing I've tried works. I tried mounting the file from the Unlimited Folder but that doesn't do anything, I tried maybe copying it to different locations in the main game folder but that didn't work either.
I did have some odd errors when first installing the game, but after I installed the English patch everything ran fine. Well at least all of EXTRA ran fine
Here's an image of the message I'm getting
