Appears to Connect to FTP Site - Won't Display Files

It appears that I'm connected to the FTP Site, but files won't display and I get this message - "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."

I get this error message with all 3 of the FTP Sites I try to connect with.

Any ideas? Something in Setup? I used all the default settings.

Thanx in advance,
