Posted this to the Relate+ forum as well but this seems to get more traffic.
I have an enterprise license running 4 CMS6 sites under one instance of EPiServer which works fine. One of these sites is a Relate+ 2.0 site. We get the following issue: "License ###### is already active for a different instance on the current machine. "
This issue is negated if within IIS we start the Community site first, then visit it and log in, effectively initialising the license for this site. Then we start the other sites and the issue goes away. This isn't really a solution moving forward as the sites might get restarted by a Windows update or something and then if the Community site isn't the first site hit this error is thrown. Is there any way around this or is this because you cannot run Relate+ with a single CMS instance running multiple sites?
