Fire wall problem

I have just upgraded to Avast 2014 and now I can not RDP to my desktop via OpenVPN. I have no problems getting to other desktop that are not running Avast 2014. I have turned off the firewall feature, but still have the same problem. Any suggestions?

I have now upgraded to Avast premier, because Avast support told me that the internet version that I was running will stop any VPN traffic. I still have the same problem. It only took a support 35 min to answer the call. I am very disappointed with the support that I have received thus far.

This is 300% BS. Any details about the support call?
