Can’t Log in!

Hi.
I recently purchased a hosting package with blue host and uploaded wordpress and then my chosen theme. I cannot, however, login using my …/wp-login.php page as it says ‘internet explorer cannot find your page’.

If I go to the site though and click on Site Admin it lets me in but several parts do not load such as the image uploader. I have never had this prob before with my other wordpress sites.

Please help!
