You Windows users have been trained like Pavlov's dogs to respond to every computer problem by rebooting. Rebooting won't solve a connection problem through the Tor network. This is all you can do: 1) Refresh the list of relays 2) Get a new identity (build new circuits) If that doesn't work, the problem is probably not on your end and there's nothing you can do about it. Look in the log file (onion icon -> Message Log). Usually the error message will give you a hint as to what's wrong. If the error message ends in "try again later", then the SR server is down or appears to be down. If it says something about waiting too long, then your client has built a circuit to the rendezvous point but the SR server didn't connect (within some time frame), which is most likely because it is overloaded.
