Receiving Argument Error

Every time I attempt to connect, I am receiving this error:

Resolving host name ftp1.tripod.com...
Connecting to (ftp1.tripod.com).
An invalid argument was supplied.
Connection closed.

It happens every time. I've restarted, reinstalled, and even updated from 973 to 974. I'm running XP with a firewall (which I've disabled and it still doesn't work). Can anyone tell me how to resolve this issue?

The program worked perfectly a week or so ago, and I had already updated. Speaking of which, I tried the "check for updates" function and it came back as "failed," if that's of any help.

It seems like it just doesn't want to connect.

Thanks in advance.
