Tell us what you are trying to do? Hi I am going to delete my site and start over completely. Will I be able to do this and still use toolset, or do I somehow need to de-register my toolset first? Some other commercial plugins don't let me use them again after deleting my site and starting over in the past, so I wanted to check with you first before I did anything.
Is there any documentation that you are following?
Is there a similar example that we can see?
What is the link to your site? mythingsandpeople.com
"Basic Account" plan only includes a single site key. It is recommend that Basic Account holders do not register Toolset in their development environments since the site key is bound to the live URL. And if you ever plan to migrate the site to a live environment, it would be bound to the wrong URL.
Based on this information, you only would have to de-register your site if you also plan to change your domain URL.
