Display Acceleration Disabled in After Effects CC 2017?

[amarism47188480]

Whenever I try to do a preview, I see flashing text that reads "Display Acceleration Disabled". I've checked the project settings and see where I can switch it from '(whatever the brand name is) software only", however it is grayed out and unresponsive when clicked. What should I do?

I am having the same problem on my mac. That video is for windows. Can anyone help?
