I wouldn't buy a used King DVD course from anyone because it almost certainly won't work.
I suppose it's a disadvantage of buying King's products, that you can't resell them, but they make sure of it by making the product node locked -- it works only on the computer that you used to register the product. I suppose if you could persuade King that you're the same person but now have a new computer, their customer service will probably assist you in enabling the product on the new computer, but they're not going to be tricked, I'm sure.
I don't know about the Jepp DVD course being sold here, but another Jepp training product that I bought, for learning to use a particular Garmin handheld GPS model, was also node locked. That was too bad, because the product was useful for only about 30 minutes of training, and then I was done with it.
Unless they are the take-off courses, then they play on a DVD player. But NO, you cannot re-download the PC based courses on another PC. The Kings make it clear that they donnot legally allow the resale of their courses. Can't blame them, I guess, they are trying to run a business. The King courses are GREAT though, worth the money!!!
I can assure you I am not trying to take advantage of anyone here. You're right, the King schools course is node locked. Thanks, I wasn't aware of that so now I am not selling that product. That said, I will never recommend or buy a King product again...
However, the King workbook I listed obviously can be useful, as well as the other items. The Jepp course is on regular DVD, so I can't see anyway they would node lock it. If anyone is interested in the following let me know, we can work something out:
Jeppesen Instrument Commercial Manual (in perfect condition) Retails for: $75.00 to 90.00
Jeppesen Multi Engine Manual (in perfect condition) Retails for: $70.00
Jeppesen Instrument DVD course Retails for: $200.00
Thanks and no worries Tim, I wasn't offended. I purchased the King Schools course about 2 years ago and to be honest I installed it and never used it, so I really had no idea that they prohibited resale. I ended up using the Sporty's product. Guess I should have read the King agreement LOL
