I have CoursePress PRO installed, or so it says when I try to reinstall from the plugin page, but when I try to add a third course it says "While CoursePress is suitable for offering a few courses, you may have bigger goals for your site. CoursePress PRO takes the features you love from CoursePress and unlocks the ability to create an unlimited number of courses. And get 12 payment gateways making it even easier to accept payments for your premium content."
I have deleted and reinstalled the plugin to no change. Even when I direct-download from the plugin page https://premium.wpmudev.org/project/coursepress-pro/
the dowladed file doesn't even say PRO
