Adding Alarms

I am trying to get OPManager to send an sms notification when anything in the routers group goes down.
When starting from
"Select a Notification Profile" ( http://server:8060/admin/ProfilesList.do?selectedNode=ConfigureNotifications&className=com.adventnet.me.opmanager.webclient.admin.notifications.AssociateNotificationBean&PAGEINFO=QCW )
Select "Pager"
Click "Next"
go to "Select a device group"
put a check in "Assign to all devices in the category"
Click "Routers" from the drop down.
Click "Next"
and have watched this screen sit at loading for over 30 minutes. What can I do to make this move along faster? I would rather not have to add 100+ devices manually.

Thanks,
Kyle
