Private Messaging plugin conflict with aMember Pro plugin

Hi - This plugin conflicts with the aMember Pro plugin (http://www.amember.com/). See attached screenshots.

1) When Private Messaging is activated, the Password "generate" link disappears
2) When Private Messaging is activated the "compose message" fields appear below the footer.

I deactivated Private Messaging for now, but can reactivate if you need to test.

Thanks!
