I installed many other WPMU plugins today and none have any issues. Only coursePress is showing this error.
Fatal error: Class 'CoursePress_Data_Course' not found in /home/rXXXXXXXg/public_html/wp-content/plugins/coursepress/2.0/admin/class-samplecourses.php on line 25
This the error showing up on the plugins page.
Server error status: Internal Server Error 
This is the error on WPMU Dashboard
Please help. THanks
