Mention of viruses in software lives on for ever on the internet so this is just a little digression to address this particular issue. That’s no virus, or WD problem. The url shows that for some reason he chose to access his site via anonymouse.org which is an anonymous browsing service. WDL is never going to work via such a site. WDL’s security/licensing is based in checking the server domain against the domain name used to issue the license. In this case the server domain is anonmouse and so that’s where it is looking for the configuration code which has the license - which was not issued for anonymouse.
