Hello, I just installed the app Lockdown 4.0 from cydia. When I first setup the app I left the password blank, and only set a security pass. Now if I leave it blank and try going into lockdown it tells me I have a bad password. When I click on forgot password and entered the security or reminder pass, it tells me the pass is (null)? I don’t have the option for letters just numbers, so I can’t enter null. I’m lost, thanks for help.
