Update failing

[wtbw]

Hi there; I have just (a week or two) ago bought flashfxp, and downloaded b902 from the official website. But when I try to use autoupdate, it goes past connecting, verifying registration, and gets to retrieving information, then fails with:

Update failed

Error: Forbidden

I am behind a hardware firewall I have no control over; it restricts incoming attempts only afaik so it shouldnt be causing this. I have no problem connecting to ftp sites or the internet. Is there any way I can easily test if it is the firewall or some other problem?

I am using WinXP professional.

Is it simply because there are no updates? I can't believe this is what it means... surely there would be a more friendly message.

Thx for yr help in advance
