Root Element is Mssing - Lands Design

Hi I have encounter the problem with launching Lands Design Toolbar.

After my rhino 5 toolbar has crashed and I did ToolbarRest, I can’t load the tool bar of Lands Design. It keeps telling me that Root Element is missing. If seems that the Plug-in is there as I can type a command to do some of the plug-in function.

I have tried deleted Lands Design and Re-installed it for a few times, but it did not work. Any one can help?
Thanks a lot.

You can load the Lands toolbars as any other toolbar in Rhino. Go to Rhino Tools > Toolbar Layout, and check if Lands toolbar is there:

If it isn’t you will need to import it manually.
