Is it possible to change the name the version is licensed by?

I bought a version of Pyxel Edit one or two days ago and I’m very happy with it.

There is only one thing that bothers me: my mistake with the license registration.

I got my version through a gift link from my father.

As I came to the page where I had to give my name and email address for license registration I was confused and instead of my name I put in my fathers name. So now my version is registered to my father who doesn’t even use Pyxel Edit. I checked the options and couldn’t find any option where I could change the name by which the key is licensed. I don’t even know if this is legally possible.

It's not that big of a problem but it would by nice to see my name when the program starts up instead of my fathers'.

Is there any way to change the name?
