Hello all. I am a firs time poster, but I have been around the forum for a couple of months now (it has been priceless in helping me learn Black Shark - which I am getting better at slowly.) I have been reading this thread, and at times I have laughed, and at times I have wanted to cry (I mean all of this in fun and not as an insult) because I know how frustrating it can be learning to use a game like this. I thought I would try to help clear up some of the confusion I see here.
Toasting Aces: I too have purchased the box version of Lock on Platinum yesterday. I have not yet installed it so I can not yet speak to the way you need it install it. Before buying it I did some research though and I think this might help you out some.
The training "videos" you are trying to use from inside the program did not start out as videos - they started out as what is known in these sims as "traks". In simple terms, a trak is a recording of someones play time in the sim, and you can watch it and if you want to, take over at any moment you want. What the creators of the game did was create trak's showing how to play the game. However, when the program was updated to correct some problems, the traks would not play in the updated program. Seeing as it would take a lot of time to update the traks every time they updated the program they just took them out of the game all together but left the menu option for them in the game. (this is the same thing that happened In Black Shark)
Fortunately, someone had made videos of the training and made them available for us to watch without them being traks (as videos you can no longer take over in the middle of the training, only watch it.) If I understand correctly, the videos should be able to be watched from inside the game - witch is what the install of the video you download should do for you (not sure yet why you are having trouble, I will let you know what happens if I ever try myself).
The good news for you is that you do not need to have the videos installed inside the game to use them. You can watch them off of the internet in Youtube. I believe there were two post earlier that pointed to Eagle Dynamics you tube page at http://www.youtube.com/user/eagledcs#g/p and also this page at SimHq.com at http://simhq.com/forum/ubbthreads.php/topics/2142529/All_of_the_LOMAC_FC_Training_M.html#Post2142529
My advise to you would be to NOT try to download and install them (because you do not understand computers that well, this might be harder for you and who needs the headache?) but just watch them on the net to learn how to fly the sim. While watching take notes of things you want to try in the sim and then try them (Even if you install the videos, you will still have to take notes, drop out of the video, start up a flight and try it - so nothing lost).
I know you would like to have the videos in the game - and you feel that because it is a game you purchased that everything should work right the first time out of the box - and to some extent I would agree with you. But what you need to understand is that you a playing a game on the PC and PC games have always needed to have updates done to them after they were released (or for as long as I have been playing them which is a long time). In this case some of the original things the program did were lost in the updates and you have not gotten a program where your copy is not complete, this is just the way the program is.
Does this make sense to you? I hope I have been helpful.
