Unfortunately I lost access to the computer on which I installed Traktor Pro and therefore I can no longer use the software with my console.
As the rightful owner of the Traktor S2 MK3 console, is it possible to obtain the same license again?
If the Traktor license is registered to your account, you can install Traktor on another computer.

Also : If you have already registered the serial in Native Access using another account that you have no longer access to then you will have to ask N.I. support to help you ! Check this article ! "I Have No Access to My User Account"
