When Dial Data has bad data for A/D, NH/NL, I will often check the Wall
Street Journal website (wsj.com) and correct dial/data this way. I've also
tried several EOD data vendors and if it's not this, it's something else
that they will not agree on.

Either way, it's probably a good idea to have 2+ sources for data. (1
internet and 1 direct connection) in case of trouble.
That solved it for me.
