I have installed SptBot S&D 1.5.1.15 on my PC as I am running Vista Ultimate build 6000. When I try to update I get the message "S&D Updater not responding". My PC processor has a 2.4GHz Intel Core 2 Duo, 64Kb primary memory cache, 4096 Kb secondary memory cache. It is a new machine and dust and or overheating is not a problem. Anybody have any clues please.
