Lost folder password, but know the master password..

Hello,
My encrypted folder has somehow become disassociated with Espionage and now just shows those three folders rather than asking for a password. I've read the other posts but I'm unclear as to whether the master password can save me here..
If I drag it back into Espionage to re-associate it, don't I need to know the password for that folder?
If anyone can help me, I would be so grateful. I can't bear to think about losing this stuff.
