Should show you how on the page, if you don't need the tunes on there delete them.

 

If you can't get it to work, you can chat customer service and they'll connect to your computer with you on the phone to see what the issue is.
I had issues with mine and they were more than happy take the time to help out and get it resolved.
Hope that helps.

 

The sct can only hold 3 tunes. You will have to delete one so you can put the new one on.
