When I install Org Chart on my domain it tells me that my license has expired

Reviewing different articles and publications about Plumsail Org Chart I have found it meets what my business requires, but first I would like to have a test to see all its functionality before buying it, today I decided to acquire the trial and when I want to add Org Chart in the web part of my site tells me that my license has expired, Can anyone tell me how to fix it?
