Cancel Flight Alert fails

Set up alert for SOO 597 11/12/15. Email and Push to Device enabled.
No apparent way to delete Alert.
Attempted to remove email notification or Push to Device and received msg “Please confirm your information and try again” upon clicking Save.
Attempted to remove both and received msg “We’re sorry, but Flightaware has encountered an unrecoverable erro and is unable to process your request at this time.”

Did not find option to include email address, so I presume that is within the account setup somewhere.

Is there a place to verify that version 5.0 (44) is the actual version running?
