Hhhheeelllppp

i went away and so i locked one of my disk drives and also locked my
user account so that a guest user wouldn't have access to any of my
stuff. Now i came back and tried to log into my account and it wont let
me so i went into guest user and tried to unlock from there but its
saying system file cant be found. My password is working because some
programs asked me for authorization and it worked but i cant get any of
my files or log into my account as it seems they've vanished even though
the icons are there. I am running a windows vista. I hate vista. Please
some help.... Please
