I have tried for 3 days in vain to get cbpi working, but without success ... with your guidance it worked fine. thank you! 

I was going in circles trying to get CBP v3.0 running and your clear directions about manually installing missing modules fixed my problems. thanks much.

Thanks soo much for posting how to get CBPi3 working. I had spent days until someone sent me a link to your page. Cheers.
