Cubase won't remember VST folder paths

Ok, I’m actually using Cubase 5.5.3 (64bit), but that forum is as good as dead, so I’m asking here. It’s a fresh install of windows and Cubase since I was having issues that I could not resolve. So now, I can’t even go into the Plug-in Information section and add VST 2 folders. I mean, I add them, but it just forgets them the next time I open Cubase, so it’s pointless. Any ideas?

This could be a folder permissions issue. Try giving all users and system access to the folder in question.
