I set it once, but then I, for some reason, didn't feel like I need it, so in the setting I reverse it to "off", now I want to set a new one, the proble is every code I type does't work and "code error" apears
I think that has something to do with the old one I set, although I set it to off, I thought that'd make it just go

my problem is, I forgot the old one, what can I do?
