Something you might want to try (although some people will say the drivers are of a quality less than optimal) is to fire up the Saitek/Mad Catz joystick control panel. I have an X52, and if I don't have the control panel open in the background the pinkie button does not work (and so I cannot access the UI), but with it open I can.
Anyway, let me welcome you to the Elite: Dangerous Galaxy. My rule 2 is; Have Fun (it is just a game, but WHAT a GAME!).
The learning curve is so steep that the mountain goats go around in teams, roped together (and even then they may fall off, but that means the Vultures get to eat!). However, when you master something, and do it well, the buzz is worth the effort.
Now, Rule 1, which is; Never Fly if you cannot cover the REBUY. REBUY is the insurance excess on your ship, and is 5% of the value of your ship (including all upgrades, but not the cargo). If you get killed, and you can cover the REBUY, you will get a replacement ship identical to the one you lost. However, if you cannot cover the REBUY you may well end up back in a basic Sidewinder. Please do not let this happen to you, as the forum is littered with tales of woe when other Players have ignored Rule 1, and then got killed.
When you decide to buy a new ship, try to have 200% of the purchase price first. That way you have enough for the ship, some basic outfitting, a couple of loads of cargo, and a couple of REBUYs (just in case). If you are trading in a ship, take it back to factory spec first. When you sell any ship you will always take a 10% hit on the value of the ship at the time of selling. However, if you take it back to factory spec first you get back the full amount that you paid for the upgrades (at this time, at least). Then, when you sell the ship, your losses will be reduced. For example, I have an A Rated Cobra MkIII worth 10Mcr. If I were to sell her now I would take a loss of 1Mcr. However, if I take her back to factory spec and then sell her my loss will be about 35Kcr.
Have fun, fly safely, and see you out amongst the stars. Feel free to ask any questions, we all had to learn somewhere, and those that care will answer all they can.
