Hi after I saw your message I went back to one of my test systems at the office that was running xampp 1.4.16 and logged on. I knew that I had seen that notice before and there it was on my log in screen. Try turning off your firewall and then logging on. If it works like I think it will it means that your firewall was preventing Apache.exe in wamp from accessing the localhost at 127.0.0.1 port 3306. Hope that helps.
