Thank you for the real reply, unlike the obvious bot in here with the moderator position that hides behind template responses that might even go against it's own rule about discussing technical topics by providing no useful information at all about the topic! Didn't even address the contradiction between the list of supported devices, and the activation/install page showing it's not supported!
I had been reluctant in "contacting" customer service up to this point because that's what the activation page is supposed to be about. Besides, I'm a tech kind of person too, and if I can't figure it out on my own, I try to learn it, if I have to, by researching or asking questions. And I don't like talking to people over the phone, lol. It always seems like either a sales trap (and I know I don't have the social skills to play the game) or attempt to hide useful information that others (like myself on a forum) might actually benefit from, if only the correct information was provided.
I did search for CM3000 (I didn't think to search CM2000 too) before posting anything, and there's only one or two posts about it.
Again though, thanks for the real reply.
