Change email address on previous purchase of webcamxp

I purchased webcamxp 10 years ago and my email address has changed. I would like to update this to reflect the correct info when I enter registration info. How can I do this?
Thanks

Hi Ronald!
Please, contact support from the web site Netcam Studio - Network Camera Surveillance Software and they will assists you.
Maybe it is time to switch to Netcam Studio at the same time ;).
