Hi @스터펌50822550 ,  I have added the email you shared to the prerelease program. Please check for an invite email.

My email address is m3921@pumster.com. We will share your email.

How do I share my email? I sent an email but didn't get a reply, so I'm leaving this here.

If you are not able to access, could you share your email? I will mannually add you to the list and you should receive an invite afterwards.

It says I can't access the trial version. what should I do?

Hi  @스터펌50822550 , this should be fixed in the our Blender add-on 2.0 prerelease. You can download that here:
https://www.adobeprerelease.com/beta/3DF9B9CB-7B2C-4B54-E279-86F9A93E82CD 

The add-on currnetly works with versions 3.0-3.6, and we are working on 4.0 support.
If you cannot acces the pre-release you can reply with your email and I can manually add you.
