works fine for me. reset your IP address or your connection, either by menu options or just unplug your router for bit. or could be issue w/ your local server.
remember, everything is a web, a strand can go down and effect just a town, city or even just streets at times when everyone else is fine. at times state or zone black outs happen. but from the big power outage yrs ago in canada, ny, ohio, we all witnessed the web itself learned on its own and rerouted around it. has it gained intelligence?
ps: if you are using explorer, try firefox, you might of got a bug on explorer preventing it, explorer has been attacked a lot lately by bugs, spam, etc. I run both now.
