The weather.com did change their server's IP address so the current conditions aren't working for the moment (and I'm using IPs in Argon cause DNS support required recompiling PS2SDK or smth. like that). Anyhow, I'm going to release a major update in a few days.
@Anyone asking for the source:
hip203 has contacted PS2Dev maintainers about adding Argon source to SVN, so I'm going to upload it there soon.
