Help with Licence \ Registration

[futura]

I purchased this program a couple of years ago. Since then I have stopped using the email it was purchased with (yahoo).
I have searched for a way to contact and try to get my licence key.
Can anyone help me out?
Thanks

Edit:
If anyone else is searching for this you can email support@makemkv.com
Just found this in another post. Ill reply with the results.
