Mesh Edit not displayed in Grasshopper

I hope somebody can help me! I downloaded the recend MeshEdit from Food4Rhino and did the installation as instructed. The Files are in the Components Folder and UNblocked. However, Grasshopper won’t load the MeshEdit components. In the mesh tab I can find the usual mesh components but not the ones that should come with MeshEdit.
Does anybody have a solution for this problem?

I’m using Rhino 6 on a Windows PC.

best, Felix

Did you have any older versions of the MeshEdit components?

I downloaded the recent one but I saw you can still download the older versions before. Do you think that could solve the problem?

I dont think so. Did you restart rhino?

Yes I did.

Have you unblocked them?
