Yea I honestly don't fully understand how many cores my commercial license uses, but every now and then it tells me that I need to register my license when it is already registered. After some digging, I figured out that I could only have 4 instances open at a time and sometimes Windows would keep one running in the background which would be 5, so I would have to close it out in the task manager and it would then work again. This made me sad.
