My 18 yo son also started this same tutorial and made it thru the 3rd video. I am so happy I am able to have this experience and help him. When my wife could not import assets she went to bed (she has a mild cold), and after I got the program to finally import the assets My son Titus sat down next to me and started the tutorial.
This was awesome way for me to spend time with him. Whats nice is if he starts getting flustered its easy for me to see where the error is- 99% he would capitalize something. THis has given me wonderful saturday:)
