I'm desperated and frustrated! Maybe somebody can help me!!

I tried so many times to connect but it doesn't work. Believe me that
the problem is not in the hostname settings. This is for sure correct!
I thought the problem was in the firewall. I checked and the programm is not blocked either...
Each time I try to connect, this following message comes:
Can't establish connection --> ftp.streamload.com:21 @ Fri Mar 31 10:35:21 2006 (0-5)
What else am I doing wrong?
If anyone could help me, I would appreciate sooooooo much!
Thanks a lot!
