i didnt know i sent it to dlsite encrypted, you'll need to rip the game to install the patch.
i posted a mega link to the ripper here with instructions
the rgss3a file is basically a zip the game reads from.
EDIT: One problem I'm having though, I'm trying to extract the files, and it says success, but I can't find the extracted files anywhere! Any idea what's going on here? Do they get extracted to some new folder in an obscure location or something?
NEW EDIT: Nevermind, putting the decrypter into the same folder as the game somehow made it work.
