Harmony 15 premium crashing when exporting in .mov

I just finished my year long license in Harmony 14 advanced and had just updated to 15 advanced which worked perfectly. Before choosing to upgrade to Premium (cause I will be needing nodes in my animations) I chose to download the trial for a test drive. It works perfectly okay except when I want to export in “.mov”. Everytime I do this the computer freezes and won’t let me export anything at all. I had been working perfectly fine with 15 advanced and had exported even bigger versions of this file before and it all started when I switched to the 15 premium trial.
Can’t upload crash log cause my whole computer freezes and I have to manually shut it down.

I’m using an Asus U43jc running windows 7.
