@M-S-MI had the same problem; the Gizmo Beta expired and guess what? It broke the BN-2 Islander. Really X-Aviation? You are going to suggest something that expires for us and then breaks the aircraft we paid for? In my experience, X-Aviation's support is garbage! I had another issue with this damn Gizmo64 plugin awhile back that I finally figured out it was conflicting with ProjectFly. I had no idea why my Saab 340 X-Aviation aircraft wasn't working and had to figure it out myself since X-Aviation's support told me it wasn't their product with the issue. Now with the BN-2 install, to have them suggest the Beta version of Gizmo64 to be a better/smoother experience to only break the aircraft once it expires without a warning or notification to update the Beta version is absolutely unacceptable in my opinion. The only reason I thought to think of it being the Gizmo64 plugin was because I was getting warnings it was going to expire and once it had, the next time I loaded the BN-2 Islander it wouldn't power on (battery was dead which I thought recharging would solve it). I feel sorry for the developers (TorqueSim) for going through X-Aviation to sell their product because it is a great product. As far as I can tell, and I may be wrong, it appears X-Aviation uses the Gizmo plugin to protect the software they sell from being pirated. Thanks X-Aviation; it's great going through this hassle and wasting our own troubleshooting time so you don't have to worry about pirated software (if this is the case?). Even it this is not the case, either way I would advise you to give an upgrade path to customers for the Gizmo64 upgrade before it expires and breaks the aircraft they paid for. The BN-2 Islander may be the last product I buy from X-Aviation; I have had it with them. @Cameron, for you to tell us to "Relax guys, things are fine!", we shouldn't have relaxed. They weren't fine.
So how did I fix the BN-2? I had to uninstall and reinstall the aircraft choosing the stable version of Gizmo. Nice to know x-aviation relies on it's customers to be Beta testers and provide hardly any support other than, "Relax guys, things are fine!". This is the only consistent kind of support I have seen from X-Aviation; we don't want to do any work, let's just hope it doesn't break. Typical from my experience with this reseller.
Blue skies!
