Yeah I can find it in Aurora, but when I try to open the .rar file, it says its corrupted. Is there something I should be doing differently, or can I get it straight from the website?
It's DEFINITELY included in the files I sent to be posted for Aurora.
That launcher probably wont work. It's for that particular version. The game has specific code in the .exe that has to be manipulated at launch so the anti cheats don't detect the trainer. It's unique each version.
You (the users) will have to contact 0x90 and ask him why Aurora isn't showing you attached files OR how to access them if there is some special instruction for that in Aurora.
