Hi,

Your project still contains references to the trial assemblies. Select all MindFusion.* files listed under the project's References section in the VS Solution Explorer and delete them, then add the assemblies again from where you have installed the full version.

Alternatively, open the project properties window -> Reference Paths tab and add the installation folder of the licensed version to the path list. In this case also make sure the "Use specific version" property for the references is disabled when you select them in Solution Explorer.

I hope that helps,
Stoyan
