I have been using a program (EPX 5.5) for year which allows uploading of photos to a website (eventpix.com) and I have not been able to access the site lately. I get "no reply from server" notices. Eventpix.com support suggests some setting on my firewall or in Avast is preventing access. Recently, I switched to Avast free edition anti-virus and I use Win XP firewall. What settings do I need to adjust to allow access to eventpix.com?
