Hi,

I had exactly this, and so I called their IT support. I think that I stumbled upon two separate bugs, but one of the bugs is this, and they recognized it right off the bat:

If you are trying to book for someone else, and you put in their name and whatnot, DO NOT check the box for including the name of this person in your permanent online file - it leads to a glitch that sends you to an error page with a note about some secret password.

I had another "server error" on the weekend, and I could never get around, whether I was using PC or Mac (OSX 10.4.8, with Netscape/Mozilla, Safari, Firefox). It is not a browser problem.

When I called IT, I don't think that I was routed to the Delhi centre, and they helped right away. Obviously this new interface is very buggy.
