Problem with adding words

Hi,
 
 
Running the app for many years now.  Love it, thanks for making it.
 
Having a problem with how Vista is playing up.  Getting an error message that en.pws cannot be opened for writing.  I go through the motions with the Plug-in manager to reinstall.  All works.  However, after closing and starting Notepad++ again, back to the same problem.
 
The seems like Vista permissions are conflicting.  How can this be (easily) fixed, please?
 
 
Thank You,
SHD
