EndNote X7.2 Trial Freezing on multiple platforms

I have downloaded the x7.2 trial version for both my macbook at home (running osx) and my desktop at work (running windows 7). I have MS office 2008 on my mac and office 2013 on my work computer. The trial version will let me put in one, maybe two, citations and then it crashes. It is impossible to work with and it doesn’t let me insert citations from the web either. I recognize that the goal is for me to purchase the full version, but I am having a hard time wanted to spend money on a product that crashes within five minutes of opening it.
