If you changed the name of the folder when you uploaded the theme originally, you’ll be able to install the theme just like any other theme…no need to remove the existing one.
Otherwise, you can unzip the live.zip file you downloaded from this site. Rename the folder live1 and then zip it back up again. Then you can install the theme like a new one.
If you don’t have a way to zip up the folder, send an email to support@organizedthemes.com and I’ll send one back to you.
WordPress won’t delete the the theme directory, so only themes with different folder names can be installed via the theme installer. It’s crazy, but that’s how they made it.
Let me know if you have any trouble,
Bill
