Hi, I hope that someone can help me and it may help someone too.
I had installed a TP-Link usb wifi adapter. Since then was impossible activate the license. I connected again the ethernet cable and it still happend.
After many tests, the way I foud to solve it is that each time that it lost the license, f.e. when launch a batch render, I have to shoot down the computer, disconnect for a time the power cable, connect it again, restart and activate the license.
Anyone know how to fix that problem. Thanks a lot
