Hi, think i have a slightly similar problem. Anyhow, here`s my issue. I have been trying out Houdini Apprentice HD on a virtual machine on my macbook pro. I eventually had to delete said virtual machine as i encountered several problems using another software. Now i set up a new virtual machine on my macbook pro, fixed my problem, but now my Houdini apprentice licenses are invalid. now is there around this or do i simply have to purchase new licenses? What can i do with the ones i currently own if i cannot use them?
