SCREENS VCN

i dl TIGHTVNC..WHEN OPENING IT ASKS FOR AN AUTHENTICATION CODE. I did not receive one. I have free non commercial edition. I have sent email to TIGHT site asking for code. The app is complex for my 76 years old understanding. I want to use iPad for flight sim controls so need free easy communication between iPad 3 and my PC. Any advice welcome.
