Not able to remove Plug in license


I am testing to support Lan Zoo licensing in our plug-in. I used the samples on rhino-developer-samples/rhinocommon/cs/SampleCsWithLicense at 6 · mcneel/rhino-developer-samples · GitHub and rhino-developer-samples/zoo/SampleCsZoo at 6 · mcneel/rhino-developer-samples · GitHub

I was able to create a lan zoo plug in and sign it - as well as the .rhp file and on the first run of the plug-in after I was prompted to enter a license. Now, the problem is that I can’t ‘release’ or remove this license which, for the sake of testign our licensing procedure, I must do.

I can see the license in the Rhino options->License but clicking on Change your license Key doesn’t do anything. Thank you for any ideas or help.
