Okay, I have no idea what to call it but I am assuming it has something to do with my registration key. This has happened to me once before to this extreme and this is the second time it's happened and is making me want to just quit. Anyway, pretty much consistently, every other time I shut down or restart my pc, it makes me put in my reg key again, Sometimes, it reverts the whole game back to defaults(graphics, bike, controls). And on this occasion, the terrain.hf file in the track I was working now just says NULL,

and once I got it fixed, when I start the track, the game just shuts down after the bikes loading screen is done. No crash message, nothing. The first time it happened I assumed I didn't close the game right or something, I don't know. If I could get some help on this I would be very grateful, Thank you in advance.
