HELP — PLEASE! I Messed up my blog at NamasteMedia.com

I tried to make my about page the main page of the blog by inserting the address of the about page in Blog address (URL) on the settings page. Now my blog is gone and I can not access the control panel. Someone please take a look at it and advise. Thank you in advance! Namaste
