Is that a plugin? Which one? If it’s a paid version, you need to contact the people you purchased it from – as commercial products are not supported on these forums.

Contact the plugin’s vendor. Please note that these forums do not support commercial products. Only the free plugins downloaded from https://www.ads-software.com/plugins/.
