If your timing out its likely not going to be related to your install, it sounds like a network issue, A time out happens when a server takes to long to respond. Please post your connection type ie ADSL Cable etc and weather or not your going through a router, you could also try turning off your firewall if you have one running the fact that you were able to connect leads me to believe this wont be the issue though.
**edit**
If you are running through a router please post the make and model
