Right click on your folders, properties the you should see a security tab, in there you'll see a box for permissions, make sure "you" have full permissions set, use the edit feature to do it if you need to, Vista defaults to Full permissions for System only!
Earlier versions didn't filter it down to the sub folders, I don't know if this is still how it is or if they updated it, you'll need to see!
