A little more information about what you are doing and what software you are doing it with would help.
I would suggest:
1. read the thread on a similar topic started by macmac below.
2. Log in to your Bravenet account and check that you have your FTP parameters correct.
By the way, in Bravenet the word "publish" is normally used to refer to a function in the Website Wizard.
Make sure that you have the correct URL for your website. I hope you saved the email or info somewhere that tells you what your URL password etc. It is the introduction from Bravenet that you got in an email.
If not just get a ticket and ask them what your URL is.
Read at top of site on what beginners or free sites are supposed to do.
Then make sure you do have the correct information.
Most people do not like to use the wizard but it does have a utility that says finish site and publish. There is a button to that effect. Click it.
