Problems between Logic 9 and Logic X

Hello. I have had to buy a new Macbook Pro due to the old one dying on me and am trying to finish a project which was made on Logic 9 and must be kept on it, while learning Logic X, which I've managed to avoid till now.

I have 2 questions:

Firstly, Logic 9 will not open old songs once opened on my new MacBook...it crashes every time. I understand this is because the MacBook is running El Capitane instead of Mavericks, but I need to keep working on it, however imperfectly. If I click on a Logic song itself it opens in Logic X instead....how can I change this? Is there something in preferences that allows me to open a song in 9 instead of x?

Secondly, if I do open an old Logic 9 song in X, there is no record button. I can record by pressing R but this is a nuisance. If I open a new song in X the record button is there. My audio interface works fine. Just no record button. Does anyone know why this is?
