I don't know how it works now, but in previous versions you had to unlock LFS (as demo didn't required an account), and the you have full acces to S1/S2 content. I guess this is automateicly done, but you could try it.
If you have any doubt about your installation state, the better you can do is unistall and make a fresh install. Be sure to not install it in Program Files folder (in Vista and Win7).
PS: I think you could rewrite you post so it makes a bit more of sense. I'm still guessing if my solution has any to do with your problem xD
