Treesloth GHA assembly loading error


after I upgraded the last version of Kangaroo2 the tab of components related to the library Treesloth has disappeared.

Now, each time I open grasshopper I get this message:

An error occured during GHA assembly loading:
Path: C:\Users…\AppData\Roaming\Grasshopper\Libraries\Treesloth.gha
Exception System.IO.FileLoadException:
Message: Could not load file or assembly ‘file:///C:\Users…\AppData\Roaming\Grasshopper\Libraries\Treesloth.gha’ or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Exception System.NotSupportedException:
Message: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See for more information.

I am on Rhino 5.

Any suggestions?
Many thanks in advance.

Have you unblocked the files?

Thanks Keyu,

I have just fixed it unblocking with this: (16.5 KB)
