Hide by User Role from CubePoints Manage Table

http://wordpress.org/plugins/cubepoints/

I know this is not a WPMU Dev plugin or something natively available, but hopefully, someone can help me!

I want to modify the CubePoints plugin to not show users with a certain user role in the table of the "Manage" section of the CubePoints' dashboard.

I'm okay making a core change to the plugin if someone can lead me through this. Please respond ASAP. Thanks in advance!
