I'm not able to copy profiles either and it's really a pain in the butt. Pitbull has so many configurations (which is awesome) and once I get the layout I like, I need to copy it to other profiles. This rock config seems really glitchy so far. I've had numerous problems with it too.
This feature has been abandoned as far as I can tell. Despite being the most commonly reported problem on the forums and on JIRA, and existing for three months now, the author has not responded to the issue of profile copying once. Pretty sure he's decided to just forget about it at this point.
Your options are to use DUF, as mentioned above, or to use the pre-Rock version of PitBull from early September.
