Glad it's working
Just a couple of things that may interest you:
1) The game experience is soooo much different (for the better) when you're using a joystick. Do consider buying one. There are affordable options. You can then look around with your mouse, which is critical (untill you buy or build a head tracking solution, that is, eh eh). There are also rudder pedals, but some joystick models support the rudder function by twisting the handle, and a lot of people have that, I guess.
2) It's a great decision to support the game. And it is indeed a wonderful game. Often there are discounts, you may want to use that. You should be informed, however, that Rise of Flight will slowly be giving way to the new game that is coming out, Flying Circus, which is part of the IL2 series, by the same company, which so far included only WW2 stuff. This new game is now in Early Access, which means you buy it with a discount and you get access to whatever the developers release every so often. Currently this means two planes available, DR1 and Spad III, and no specific WW1 maps, etc. It's also not polished, it's a work in progress. It will take a while (a few years, maybe) for this new game to cover the diversity of material that Rise of Flight has to offer right now. But it runs on a new engine, and it enjoys the benefits of new technology (VR support, etc), so it's the way to the future, and most Rise of Flight players are very excited about it.
