[users] Password protected files

[Dress-Ups Ltd]

I've downloaded open office 1.1.4 and transferred my files into this system.  
Now it won't allow me to open the files I put passwords on!  I know the 
passwords but the error message You are not allowed to open Password protected 
files' comes up.  Help!
