i only got the map loader to work with xp, win 7 64bit had no joy, same goes for NSU, works in XP but not Win7, not sure bout vista!!!

Plus u must have the N900 as a Mass storage device, so when u look in my computer u see to new storage drives, 1 should show a lil pic of the N900... if not unplug and plug back in, this works on a VM machine if u have win7 or having probs with vista install vmware with a copy of xp on it and ur gd ta go!!
