Login problems after hosting move…

Hi all
I’ve moved my hosting and domain name to another company and re-uploaded my backup of all the wp files to the new server and also imported the MySQL data into a new database on their server. In doing so I had to change the database name and password. I’ve changed the wp-config to fit and the site is semi-working (considering it’s a temporary site until the domain propagates around the web) at –

However, I can’t login as I did before, I used “admin” as the “login” and then my new password with no joy. I’ve also tried the using the new database “user” name and the associated password with no joy.
I can’t find where the login name should be if it’s not “admin” by default. Should it be anything else or can I change it in one of the other wp- files?
Or is it just a propagation thing that will settle down over the next few days?
Cheers
