After installing WS-4 I would get a "Connection Timed Out" error or "Cannot Locate Server Error" when I attempted to unlock the program. The problem turned out to be my Norton Antivirus/Internet Security Program. For some reason it wasn't giving me the usual pop-up when a program trys to connect to the internet that would prompt for permission, so I never suspected it. However, after disabling it, WS-4 connected and ran fine. Some users may find that they also have to temporarily disable their firewall in order for WS-4 to connect to the internet since it uses SOAP/port 80.
