nike+ and proxy problems

Hi ya.

Have used nike+ with the nano ipod for about 6 months now.
Have been uploading workouts through work with no problems getting passed the firewall, and having to use a password for the proxy server.

Last week nike closed the site to move it to what they termed a "larger roomier site". Ever since I have been able to visit and log in, but can not send my running data through the proxy. It allows me about 5 attempts, then kaputs and syncs everything else. and comes up with message that it cant send to nikepluscom site. nb. i use my proxy password to access alot of sites through browsers and email, and I have not had any problems so it is not my password.

Is there something extra I can do in the systems pref. to get through, or open a port. I have googled but kind seem to find anyone else with this problem. I even have tried this on other mac computers at work, and it comes up with the same issues.

help pretty please
