Help With Blog Pls

Our blog was hacked into and unfortunately, I had to delete everything and try setting up again. Here’s where I’m getting stumped. The “new” blog gets set up, I get the password and an email but then when I try to log in to admin, I get the error message below. I have tried deleting the blog including database and trying again quite a few times over the past couple days and I am still getting the same message. The same thing happened the first time we set up the blog, but after a couple deletes and reinstalls, it worked. No such luck this time. Would appreciate any help.

Thanks a lot.
