Hi Urs,
I have the same problem,
I have re-installed the program and everthing works fine. The program connect to VATsim and FSX, the problem is i can't connect the traffic button.
The sentence under the program is : "authentication of aivlasoft online data failed" (yellow ball). When i click on it de Yellow ball will be green. (connected to data provider)
The traffic/wind/optv button isnt activate. Only the Vect button is white
Is there a sollution to fix this, before it always works perfect.
Kind regards,
Sander
