I have seen several comments with other people that have had problems getting the feed. I am no techy but I finally got it up. The problem was apparently with the REalPlayer - when I loaded it to my desktop it never connected to the RealPlayer web site to register. And if it wouldn't connect for that, it won't connect for AA. After fooling around, working my way through the Real Player suggestions - I knew it was a setting problem but couldn't figure it out. However, I have a newer lap top, so I loaded the REal Player to my lap top - came right up!!
My laptop is newer, but XP also.
I know that everyone may not have a spare computer around. However, if you haven't gone through the REal Player help on connection settings, try that. There were several things you could do.
