having issues trying install an external plugin

Several months ago i purchased the plugin software at [ removed ] and my web designer installed it for me. unfortunately it was not installed correctly in other words nobody could post and it did not have all the demo features. this went on for a little while with me trying to get some support from the them . to cut a long story short the issue was not resolved and mu support with them has expired.
a few days ago i attempted to have installed it myself via my wordpress admin panel and it appears to have been installed correctly. i even managed to input the license keys corretly and i have a message telling me it’s activated with a tick next to it. that is great however when i go to the webpage
it still shows the default wordpress page. considering cutting my losses and using another directory possibly a free one. however i do like them and dont really want to lose my money on the purchase. is there anyone using the software or at least are familiar with it who might be willing to help.
thank you for your help
