cloning to my new location|Old Forum|Forum Archive|XCloner

I want to move my existing joomla based website to a new domain name.

I have created the backup on my old domain name.

Ive gone into restore backup and selected clone button.

Ive entered the website URL of my new domain name
and hostname , usernaem, password and directory of current website.

Its successfull untill i click on the link to move onto the next stage.

All i get is a 404 error page.

can anyone tell me what Im doing wrong???

thanks
