i had a problem like this over the summer
not sure if it is the samething going on with you, but yeah i could never get on the rx, on my girlfriends comp. i could get on fine, so ..
but there was some problem with my browser reading javascript, so i had to reinstall internet explorer 6, and then i installed a different program to read java
now everything is working great
let me know if this helps or if you need more info. or sites to check out
