cant get my n-track compressor to work

how to activate

i bought it a while ago but had to refomat my computer.
i registered n-track but it says i only have a demo of my compressor. what do i do?

contact N support

…or see if you can find the email that was sent when you bought it - or the download link that was sent in the email.

In pre-V4 n-Track the compressor was a separate, downloadable, product. It’s free in V4
