Can not add interfaces to monitor for bandwidth... HELP

Can not add interfaces to monitor for bandwidth. I have tried using both the V1 and V2c options and the program wont even let me add a single interface yet I can see the list of interfaces on my router. I just upgraded to the professional version and can't for the life of me figure out why this simple task is just not working.
