Hi, Setting up Slingbox 500. Everything went fine until I tried to enter my zip code during setup. The remote was operating well during the first few steps. However, nothing happened when I pressed "OK" after having entered the zip code. I changed remote batteries but that didn't help. I started setup over again and the same thing happened. The first few steps using the remoted and onscreen instructions went fine but I'm stuck on the zip code. Any suggestions? Thanks!
