Ubuntu :: Can't Use Symantic Anymore?

I have ubuntu 10.04 and lost the ability to use synaptech package manager. I was able to use it yesterday and everything was fine;however, yesterday evening it stopped seing my internet connection. I am connected to the internet I can surf the net, but when I try to use ubuntu software center it says "Failure to download package files" and in the in the details it says " cannot connect to [my ip address]:8080 ,now 8080 is the port that i remember closing like this $ sudo uwf delete allow 8080", so i tried to open it with $ sudo ufw allow 8080" but that didn't work, so i tried $sudo iptables -F even though i never installed firewall but that did nothing either.
