File sharing issues Vista and Leopard

Hey Everyone

I;m running os x 10.5.6 on a macbook and windows vista on another laptop. I can't connect to my printer wirelessly from the laptop (not compatible), so I want to be able to print files on my macbook from the other laptop (which is connected to the printer). I've been using this
http://www.simplehelp.net/2008/07/17/how-access-the-files-on-your-mac-from-vista/
guide in order to help me make it work, and ive looked at alot of other guides that say the same thing. I have all my settings exactly like these, however when i try to look at the Mac's files from Vista, i can get into the home folder but then cant access any of the other folders (music, documents, etc.) It simply says access denied, does not ask for a password or anything. Anyone know why?? How to fix??
