Can't download content to my Forerunner 245

Just got my new Forerunner 245.

The watch is updated and the connect and connect iq apps as well.

When I'm trying to download anything from connect iq to my watch, the download box is unclickable with the description " get the latest version of this app, you must update your Forerunner 245 music in Garmin Express. I also downloaded Garmin express and connected/synced my watch with it.

What am I doing wrong? What should I do so I could download apps and face watches to my watch?
