I tried the demo and I loved what I saw. Now I went to the track editor and I tried to rasie the lift but I could not. When I buy the full version will it be much easier or will it take some time for me to figure everything out?
Not, sure exactly what you're asking about the lift, but the editor in the demo is exactly the same as the real one, so it'll just take some time to get used to.
You cannot edit anything in the editor, you can only see how things are done. The full version allows you to manipulate, create, etc. as you feel the need.
