Like any product, their factory support is only as good as the person you must deal with. I've had times when they responded to an email the same day it was sent. Other times, it took six weeks or more to get an answer.
I've found the best response, while also the most expensive, was to call them on the phone. You may get passed from one technician to another, but usually, you get the service you're after.
Good Luck,
Gary
