Hi @iarkgr, sorry to see you’re having problems with this.
The free version is still available. However, we made a few changes to the free license sign-up process. Existing free site keys created before the change will continue working, but all new installations require you to register for a new key.
You can see the reasoning behind why we changed the free signup process in the following blog post: https://www.wordfence.com/blog/2022/11/wordfence-7-8-0-announcement/
Please click on the Resume installation button on the site with issues and follow the instructions walkthrough video available on the links below that shows users how to install a free license, start to finish.

Let me know in case you have any issues.
Thanks,
Mark.
