Question Trying to publish a music package

Hello everybody,

I'm very new in Unity, I'm a musician and music producer.

I'm trying to publish my first music package. Everything is almost ready, I just need to upload the zip file of my track, it should be easy enough.
I purchased the Asset Store Tools as required, it's in my Assets. But when I try to open it in Unity (both on the Assets Store page and my Publisher Portal) the buttons seem not to work.

I'm pretty sure I made a silly mistake somewhere but... What am I missing??? Does the fact that I'm using a Macbook affect all this?

Thank you for your help

 

I'm a customer, not an asset-vendor, but I think you'll have better luck directly emailing Unity Store support. They do peek into the forums, but the Store forum is very large/active.
