Course Forge was installed on 1/22/2015 and the tutorials say I need Unity 5.2.3 so that is what I have. I'm not sure what the 512 package is. But thanks for the reply
I am using the original course forge that came with the game when it finally came out and Unity 5.2.3 which I think is what was used with the original course forge when all the players could use course forge it is the one that the tutorials say to use. I am in the process of re watching each tutorial video for Course Forge and taking notes.
I am assuming this version will enable me to create a course and play it by myself and even upload it at some point assuming I am capable of making a course.
