What errors are you getting?
Do the errors also occur in Filezilla (Free FTP program)?
Ah... Network (non)Solutions), a part owner of GoDaddy. I had troubles with them too. I've always been used to using a "www" folder as my root, but NS uses "httpdocs" as the root folder name or files won't upload because "the folder cannot be created".
What's the name of your root folder?
