Glad you got this resolved and you can move forward.
Please do try to give all information you can when there is an issue.
I’m more the blender side of things here at GameDev.tv so when i was learning coding the number of times i forgot to add a script or a component to an object and had to get help was not funny!
Sometimes it helps to bullet point or list and also add a time index to the video where the issue occurred for you.
Sometimes its a unity update, sometimes its our own error but the more information we can get the better we can help you 
I do suggest though taking our Git for Games course (Something i also need to do so maybe i will see you in the Q&A there as a student )
Thanks for posting your question and taking the time to let us know its likely solved.
