Change port that traps are received on in OpManager 8

Change port that traps are received on in OpManager 8

I recently had a problem with OpManager and in the end, had to shut it down, repair the DB, start and start it back up. When it started back up, it worked fine except I got this error:
 
Port 162 needed for receiving traps has beed occupied. Please free the port.
 
We only have a trial of opmanager right now, so the other program we are using for network monitoring is currently using port 162, but it can forward the traps to another port. So I am wondering if there is a way to change the port that OpManager uses to listen for traps.
