I tried to re-license and the licensing format insists my info is invalid, I don't know why this is. Is there something I'm missing? Thanks for any help.
First make sure that you're running Houdini 8.0.410 or above. If that is the case, then run the License Administrator (or hkey on Linux). From the top menu choose View > Diagnostic Information… Post that here and maybe it will give us a clue as to your problems.
