Unknown Error...But it was fine a few days ago???

OK. Finally got this up and running everything was fine, then all of the sudden I get this error. I don't know what happened and why I can't get in...Any advise? Anything?

So frustrating... :x

The most likely reason is that the ftp site is down, try to connect to other site, windows 98/98 SE/ME don't has good info about the connection failures.

Please help me...The site is not down, it is working fine for others...
I dont know what to do!?! :oops:

And the error was...?
