Sometimes there is a delay with a computer initializing the connection with the project. Your computer should have made a connection by now and received work. If so, it should appear on the website.
Does your computer appear on the website now?
no, I've only created my account after installing PTP in my first computer.
thank you all for you reply, now I don't really mind if my added computers shown or not. They are still working well, and that's enough
I downloaded the new installer. My two added computers have been working very well so far, I don't encounter any problems
Now I can see one of my two added computers in FB, the last one may need some more time )
Thanks for your replies.
