Moving Wordpress To New Host - Importing Database Error #1062

[admin]

I am moving a wordpress website to a new domain & hosting and I am having problems with this. I have backed up the whole site, imported it via ftp to the new domain and installed wordpress.

However when I try to import my old database to the new site I get this error:
