The group specified does not exist in the database [error]
Hello there!
When I try to follow the instruction I get stuck at step 5.
When I try to select the nodes I get this message "The group specified does not exist in the database.":
Where should I look for the error?

(change to the 'create' button instead of add), I just went through the steps as written in the tutorial and had no issue with this step in v2022. Also. From your screenshot I can see you are using HM 12.0? This type of analysis wasn't supported until later releases of v12 I don't think, so you may run into issues later anyway? (this is all from a very long time ago so I may be misremembering) note in tutorial says:
I would really recommend updating to a newer version, since v12 is now 8 releases ago!
completed files, if it helps

Thanks for your comment. I have already solved the problem, I actually did it in the wrong order. Unfortunately, I can't update the program as this is the only version available at my work. 
I have the latest version privately and there I have no problems. Thank you!
