Login Problem

I’ve encountered a problem with logging into my WP site at http://www.thefreechapel.com

I have doublechecked the UN and PW and it’s correct. When I put both in and try to enter the dashboard it looks as if it is “looping”. I never get an error message it just gives me black UN and PW fields again.

I’ve never run into this before. Did I do something wrong? I’m on Hostgator and running Vantage Premium template.

Thanks
