Ubuntu :: Accidental Permission Change To 'none' On Folder?

A rather new user here, was messing with the preferences on a user folder of mine on Karmic, looking for a way to make the folder invisible to users (like the old windows option). Set it to 'none', then closed it, returned to the directory finding the folder with a box with an 'x' on it.

Went to open it, it says 'access denied'. So I think 'okay, how do I undo that', go back to see if I can restore it back to 'read & write' with no sucess.

Seached the forums for a solution to this issue, most of solutions revolve around 'gksudo nautilus' which I attempted to open via command-line. Nothing seemed pop open after I entered my password in responce to entering said command-line, probably because I really don't know how to use Nautilus.
