Lost my ntrack!  How do I get it back?

Our computer was infected and we lost many programs we had downloaded including ntrack. We bought it in 2007 and we’d like it back. I have the keycode/serial number. How do I get it back? Or upgrade to the new version?

Thanks!

Hi. Go to the home page > download page > older versions.

If you had v5 codes will work in v6 Mary.
Down load the latest build 2549.
If you do that you will probably have to learn to do some editing tasks a little differently.
I would suggest downloading both and continuing your current projects in v5.
Using v6 for newer less urgent projects until you get accustom to the nature of its ways.
