I was with DirecWay, which turned into HughesNet (and this improved the service tremendously). I've been very happy with it and have had some issues every so often, though I've found the company to be responsive, a lot more responsive than others (looking at you, Verizon). I don't use the email, except for notifications, and so I haven't had problems with it. Once it stopped forwarding the notifications, but the issue got resolved.
No rush at all -- if you can share the old contract, that'd be super, but it's not a demand or anything. 😊 When you upgraded, the old contract was likely superseded by the new one.
I like Gen5, it's better than Gen 4, and I plan to upgrade to the new system (Gen 6?) when it's ready.
