Hi Lars,
You mentioned having several sites with different installations of mojoPortal at different versions.
However my records show that you have a Single Installation License of Form Wizard Pro purchased in 2010.
While my products have no locks to prevent it, it is a violation of the license to use it in multiple installations. You should either purchase a license for each installation or purchase a Server License to support multiple installations on one server or an Enterprise License to support multiple installations on multiple servers. Or only use the product in one installation.
Best Regards,
Joe
