Please I need urgent help (Views User/login nomore working)

I edditted the user views and logged out. Now I can no longer log in to my site.
if I go to www.mysite.com/user it shows me a list of all registered users on mysite and when I click on my user name it shows a blank site. Any one knows how I can solve this or do I need to completely install drupal again?? Although that will be a horror for me. I will appreciate any help.
