Help Using Trezor One To Store RVN

I just got my hardware wallet in today and I'm trying to figure it all out. RVN isn't supported by Trezor directly so you have to use a third party app and the options are confusing.

I was able to set up a RVN wallet through Chaintek and send some RVN from Exodus then back again, everything seems fine there. My concern with Chaintek is whether or not I need to rely on the website being around in 10 years while I HODL. The whole point of my Trezor is to safely store my coin for a long time, if Chaintek disappears before then what's going to happen?

I've downloaded and installed Electrum-RVN but can't figure it out. I was able to run it once but it said it wasn't connected. After closing it out and trying later I think maybe I mis-clicked and entered my pin wrong, now it just gives me an error when trying to start it. Trezor doesn't want to connect anymore it seems (about to shut down my mining and restart to see if that fixes it).

Debug message

trezor: (error getting device infos)

trezord: acquire/8/null failed with code 400: wrong previous session

MangoFarm is the only other option listed by Trezor and it seems like it would have the same problem as Chaintek, a website that may or may not still be around when I want to retrieve my coin.
