The PB support for QTP is still in primary phase. I don't think it is matured enough in terms of stability. I would suggest you look at some other tool, not sure if TestComplete supports it or not. But you can have a look
Were you able to expose all your PB objects with this add-in? I have downloaded QTP 10 trial version and installed the PB add-in as well but still QTP fails to recognise the controls in a PB data window. Any clue to it ?
