I am playing the campaign mission Alliance and am in the process of claiming the final Drath planet.  Once I concur the planet a message dialog appears where I talk to the Drath.  I complete the message dialog and then it repeats by starting the initial Drath communique, except it will not allow me to click through the message.  This then means I cannot move forward and complete the dialog and finish the campaign mission.  This seems to be a bug.  I have saved and restarted the mission, restarted my computer, etc. but nothing seems to shake the issue.

Any help will be greatly appreciated.
