[Zope] restore acl_users after removal

hello, sorry for the stupid question, but ... i removed my acl_users folder, and now need to restore it. there's no real problem with the lost data, but i'm not able to login into zope any longer in any way. even emergency user and ftp login don't work any more. is there any way to access the zope file hierarchy for placing a new acl_users folder there? otherwise ... does this mean, that there's no way any longer to access the data in zope? bye jonas
