Just to report that when I clicked the update button in the settings/reboot tab after I was prompted to update by max2play, I lost my activation. I had a preconfigured max2play with premium pre-activation in place. I did the things requested in Zalun’s post: saved the empty activation box, rebooted, put in my e-mail, save, reboot, but to no avail. Also the option to reset everything did not bring the activation back.
It may be a connection problem with the max2play server, as in Zalun’s case, and may be ok tomorrow. Hope so. I do have internet connection (ethernet wired).
I find it surprising that I got the spotify thing working, as I read a warning that I needed the premium licence for that.
