infinite loop

Hi, I accidentally created a rule that creates an infinite loop for any logged in user, in essence rendering my site unusable. I was able to remove the rules module to get the site working, but now I can't use rules as each time I add the module back in it restarts the problem.

Is there a way to remove individual rules or all of them from out side of drupal? Where are the rules stored? Would just deleting them work?

Thanks
Omar
