I tried disabling it and going to the site but that didn't work either. I was able to access on my other comp though. I guess I will watch for them on this one and book on the other.
Try booking any airfare on the regular site and then type DING in the codes. It will not let you book, but it will advise you of what problems may be (something to the affect of -- "If you have Ding but cannot book...check yadda yadda yadda).
