Hi Jauburn, please try next steps:
Restart the game in PC mode, then go to the model and try to use the mouse to press on the passcode panel, make sure you are typing the right code which is included in the rar file. It should work without problem in PC and VR modes.
Please provide me with more details of how it is not working. For example, does the passcode panel cannot be pressed or the code says it has an error?
