|Eric, how are you connecting? Wireless or wired?|
Open IE click on tools/internet options/connections/Lan Settings and UNCHECK use proxy server.
Close IE and open it again and see if you are online.
If that doesn't work...then download them on a different PC to a thumbdrive or burn a disc...then load them onto the problem PC and run them.
