Arachne server-side problem

[Or Botton]

When trying to enter www.mediastore.com I received an ASP error message.
This is not the first time that I get an ASP server-side error message
when entering with Arachne to a Microsoft based server. These things
do not tend to happen with Netscape, even 3.04g.

Any idea what could be causing this? (although I got a feeling that
its pretty obvious.)
