I addressed this via email (for the third time) last night.
As noted previously, THERE IS NO FILE TO DOWNLOAD. You install Store Locator Plus from WordPress and put in the license key on the General Settings tab.
You can look up the license key by using the incorrect email address that I gave you at http://www.charlestonsw.com/mindset/contact-us/
Changing the mis-spelling is a chore as it needs to be changed in PayPal, the license system, and WooCommerce. Having the right email does nothing for you besides giving you a way to look up your license key with the automated link. YOU CAN ALSO LOOK THIS UP ON YOUR CSA WEB LOGIN with your username/password regardless of the email typo.
Receiving a total of 14+ messages within a few hours via email, Facebook, and this forum is a bit much. It reminds me of my 6-year old trying to get my attention when I don't immediately respond... "Daddy, daddy, daddy, dad, daddy, dad, daddy, dad, daddy, daddy". Look on the website, read & understand how to use the add-on packs, and email me ONCE... wait 24 hours, and if you don't hear back email me again to make sure I received your message.
At this point I'm assuming you've received your key and figure out how to type it in the license text box and am marking this resolved.
