    Invalid Serial on second system

    ELedbetter

      When I enter my Lightroom 5 serial number on my second system it gives me "invalid serial number" error.  I have it working fine on my iMac, but my MacBook Air keeps giving me this error. It logs in to my Adobe ID and sees the product in my account info. I have done a fresh install twice and still the same error. Help!
