I get (Free) estimated for all shipping methods

I recently purchased the premium ups plugin and I don’t know what else to do. I provided the right information the plugin’s settings asked but all I get calculated is (Free) for any shipping methods added to my website. The basic plugin was working fine before. Help please. Here is the url in concern: https://www.uhs-hardware.com.
