To clarify: I have noticed that I am only getting "Error 50" now since the firmware update.

Approximately after about 24/36 hours the connection between the profilux and PC is lost and Error 50 is displayed.

Any idea if this could be a problem with the router or switch or a firewall or the P3? I am not an IT guru, so have no idea where to start looking for the problem.....

Agh!!!

Thank you!
