When i had a problem with GoLive crashing every time i launch it i created a new administrator user on my Mac OS X Leopard.

When i was transferring my files and folders to that new user i made a mistake on moving them so now i have a problem with the privileges of the folders i have. They are giving full access to the old administrator user of mine but not the new one because that silly mistake i'd made. Also i erased the old user so i can't switch to it and make the necessary adjustments. I don't wanna to do all the privilege change to all my folders manually so is there a software or an automator script that can change the privileges for me?
