Dreamweaver CS5 - "A FTP error occured, Cannot make connection to host"

So, please help me. There must be a million threads like this, but for some reason there are NO real solutions. I've now tried:
Dreamweaver 8
Dreamweaver CS5
Changing DNS-server
With SFTP and plain FTP

It must be said that neither Filezilla nor Fetch can connect.

This message states, as you know, that the reason could be wrong login info, however, the login info IS correct, since I can access my page on godaddy, and that has the same login info.

I am seriously begging you guys, please help me.
