I was cleaning up my master installation and changed my main ID. The site I'm trying to make my MASTER was originally a child site. Now when I try to install a component to my master site I get an error:

This extension is not found in the master site.
Please install it first in the master site before installing it into the slave site
Install Plugin Error

Im sure there is something in the config file or something that I missed? What do I need to change to make this new Joomla Installation recognized as my Master JMS Site?

UPDATE: I've notice there is a directory structure and I think I need move some of the Configuration.PHP files around?

UPDATE: I'm not sure, but during the process of deleting the old MASTER ID Site and replacing the new site, I went thru the installation process again and I'm thinking it rename all my old jos_ tables and created new ones? Could the possibly be the problem?

First a master website has NO id.
A master website is any website that is NOT in the list of slave sites managed with JMS Multisites.
So if you have added your master in the list of slave site then you have converted it into a slave and lost your master.

To recover a master, you can create a subdomain in your HTTP server admin tool (ie. cpanel) that you assign to the same directory that your original master installation.
As the subdomain is not present in the list of slave, it will become the new master.

Becarefull that you could have problem with the "master" converted into a slave as you may have not correctly setup the DB connectino and perhaps also make mistaked in the deployed directory.
Becarefull also if you try to delete the master converted in slave as you perhaps will delete everything.

If you want to learn how to setup JMS Multisites, I suggest that you follow the tutorial video step by step.

Edwin,

This thing is so messed up and now that I have a better understanding of JMS, what I would like to do is delete all the JMS Setup and reinstall clean.

Once I do that, I would like to some how import my existing sites database in without overwritting the database? There was a mention of how to import existing sites in the tutorial but I think that video was missing!

There is no video that explain how to import or move an existing website as this is a specific procedure for each website.
If you want to re-use an existing DB and move a website, the idea is to install all the required extensions on the master website and later create a fresh slave site in which you will create (or copy) the configuratoin file of the existing website to move.
You will also have to re-copy manually all the files that were present in your website to move (ie. images, ...)
So as you can see this is a manual procedure and depend on the extension installed on the website you have to move and also all the files and folders that you alsoo have to move (or copy).
This depends on each website and their current functionalities that you would like to move.

This is moreless like if you had to rebuild all the website based on an existing DB content.
