@cosmo Also, when I open the Aristois installation, it doesn't come up with the screen where it says welcome and tells you how to use the mods and all that. I have no idea why this isn't working so if someone could help me that would be great. Thanks.

For some reason, when I press right shift, the GUI doesn't come up. I have tried using different commands to set the key bind but it keeps saying the command doesn't exist. If there is a way to fix this, please tell me. Thank you.
