PAServer can't work

Hi, I has C++ builer Berlin installed in my computer. This days, I update C++ builder to RAD Studio because I need Delphi. But after installed RAD Studio the PAServer can't connect any more. I get "ElnvalidPointer:Invalid pointer operation" message when I press "Test Connection" Button. I can't connect to Win64 PC or MAC OSX. All I get is ElnvalidPointer. How can I solve this issue? Thanks Eric
