So, I screwed up I think... I bought a new Mac and transferred Maya from my old one to my new one using Apple's Migration assistant and then I foolishly reformatted my old Mac without checking if I had to do anything first.
I've since learned that I need to export the licence with the included utility but I can no longer do this because the old Mac has been reformatted.
After that I tried to redownload and install on the old Mac since I still have it but there is now an error when I enter my serial number.
So I was hoping someone could help guide me down the right path to get this resolved. Any help would be greatly appreciated
Ahh I got it working! I somehow managed to stumble on to a way to get a new code from the Autodesk site. I wish I remember exactly what I did in case anyone else makes the same mistake but my crisis is resolved!
