I have bought Houdini Indie, and my free Houdini Engine Indie as well. But I had activated 30-day trial version of Houdini Engine before, and it hasn't expired yet. Now I can't import digital asset into Unity because I have a trial version of full commercial license Houdini Engine and a limited commercial license (Indie) at the same time. So when I import my digital asset, Unity gives me an error:
Asset not loaded: HAPI Error: Limited commercial (Indie) assets not allowed with commercial licenses.
I have tried to return the trial version I activated using Houdini License Administrator, but it always gives me an error:
ERROR: Invalid license id. You may only return licenses that were acquired online via the Houdini License Administrator (hkey) or Houdini Online Services.
How do I return my 30-day trial so I can use my Indie license?
