Unregisterd a license - kindly advise please

I have two licenses for 2 different sites. One of them in live test phase. I went into my account and into the license and clicked on it and mistakenly unregistered it. So now I have the site with an unregistered license at Boonex. So how do i fix this?

Basically how do I register the unregistered license to the same old site?

Simple.

Take the license out of the site.

Log out.

Log back in. The site will then prompt for the license and you put it back in.

You mean go to the site>admin>advanced>variable>here i should remove the license>log out>log back into site and put the license back in.

Is that it?

Correct. When you log back in, log back in from the admin back end. yoursite.com/administration

It should prompt you for the license.

Thank You Deano. Much appreciated.
