Panda end point Error 5000

Hi great people of techyv, I am posting a problem here on installing panda, please refer first to the screen shot I pasted below.
X Connecting to the server
Error 5000. Contact your administrator Connection settings
Getting configuration data
Downloading signature file

When I read on the error, it is pointing to my internet connection, when I checked my internet connection, it seems to be no problem at all, since I can browse the internet, it seems something is blocking the path to the server, so I checked on my firewall it is turned off, so I am now wondering, why from all application, only panda cannot get through the internet, please share some ideas on my issue, thanks for reading my post.
