Well, I spent an embarrasingly large amount of late evening hours playing crosswire. I finally got to 4300 points and tried to redeem them for 2500 AA miles. I got a message saying: "We're sorry; we are unable to process your request."
So then I tried the 1000 miles and got the same message. Hopefully just a glitch that might get fixed.
As a side note, I also noticed that the games had fewer or no glitches if I used MS Internet Explorer instead of my normal Mozilla Firefox browser (not all that surprising really)
