I upgraded the McBook to Big Sur last night, and today when i open my n-Track, everything becomes super slow, and most important, when i tried to save my project to mp3 or m4a file, it crashes, just crashes!!! even i created a fresh new project without importing any audios, just save an empty project to m4a, it still crash!!! Please help to advise how to fix it urgently, attached the logs as below, thanks.

Hello Teli_Liu,

it seems that you’re using an old version of n-Track (9.0.2, the current stable one is 9.1.2).

Could you please try to download the latest version and check if the problems persist? I’ve tested it running Big Sur OS, I’ve experienced no slowness and I was able to successfully export a m4a file.

Should you continue to experience crashes or problems even using the latest version, please contact me at andrea@ntrack.com so that we can try to better investigate the issues.

Andrea
