Ops Center - Updating Patches using the Update Profile tab

I am unable to create a new profile in order to update patches onto an asset. When trying to create a new profile in order update assets, I'm unable to access any option on the "Update Profile" tab. According to the manual , http://wikis.sun.com/display/EMOC11g1/Creating+an+OS+Update+Profile , that indicates that the option is disabled and the resolution is to register and manage your assets. The problem at hand is that despite registering and managing my assets I'm still unable to create a new profile. Could somebody give me insight on what else I could do in order to carry out the task of updating assets with patches.
