For future reference, that is a rather daft subject line. Luckily for you I glanced at your message, normally I wouldn't have bothered. If you had used a subject line like "Amino 140 box not supported" you would have guaranteed it would be looked at.
Come back if it doesn't help.
Later: And a simple forum search for 'Amino 140' would have produced this : https://community.sling.com/click.jspa?searchID=141691&objectType=2&objectID=56531
