the only securitiy programs i have are these:
zonealarm free firewall
avg free
peer guardian
hostsman


UPDATE:
i uninstalled peer guardian and hostsman,restarted computer and still couldn't connect.
reinstalled them both,tried again and it connected.
very confusing indeed.

when i installed hostsman,it asked something about a DNS cache which i ok'd.
maybe it was something to do with that-i don't know.
but at least i can now access the download page.

thanks for everyone's input.appeciated.
