I have a MacBook Pro running OS 10.6. There is a website I used to visit to read e-books for free. Then one day (nothing changed hardware or software-wise), I could no longer access that site from my computer. My friend came over - with his PC - and was able to access it from my network. Today, I just accessed the site from my wife's iMac G5 (same network), but I still cannot access it on my computer using ANY browser (Safari and Firefox). I cannot access the site from anyone's network either --- making me think my MBP is doing something weird. I keep getting: "The server denies connections. The server might be too busy or might be disabled. Try again a bit later." What do I need to reset or what did I do to cause this? How do I fix this?
