Trouble logging in

i just redirected my wordpress.com blog to Bluehost.

I installed wordpress 3.1 via simplescripts on Bluehost.

It gave me a link to log in (myurl.com/wp-admin).

When I try to log in it takes me to wordpress.com.

Do I just need to wait 48 hours for the site to be redirected?

If so, is there any way to work on my site in the mean time?
