 * Hi
 * It appears you are using the old V1 interface and have installed the free version
   over the pro version.
 * Please deactivate and remove the existing plugin.
    Then, Please download the 
   latest pro version package from our My Downloads page at [https://www.flycart.org](https://www.flycart.org)
   Install and activate it.
 * Your rules and settings will be kept during the reinstall process.
 * If you face any difficulty, Please open a ticket at our support section at [https://www.flycart.org/support](https://www.flycart.org/support)
 * We are happy to help.
 * Thanks
