TraktI or S4 Service Center

if I can't really use my Mac any longer I can use my Windows but I tried it and it can't connect to the service center app to activate it.

It has a message "Server Communication Error"

So that people may be better able to help then please tell exactly what is your OS version? and what is your computer type ? Also tell what exactly is your device model ? and version Mk?

Service Center is EOL. If you are referring to Native Access then please do not call it Service Center as this will create confusion.

Then also please give exact errors or screenshot of error (best)

.

Be sure that you are using latest version of Native Access for your OS (unless using a legacy OS)

.

If using Mac then :

Compatibility of Native Instruments Products on macOS

Have you done all the Mac users must do when using N.I. software ? :

ALL NI apps including NTKDaemon must have full disk access. : How to Enable Full Disk Access on macOS

And quote Kymeia : if using Sequoia then N.I.apps must be added to the Local Network
