This is the version that runs from the sdcard and yes I do have to turn on the usb storage when I hook it up to my computer. Here is the link for the site where I purchased my sdcard from;
http://www.rootmynookcolor.com/. I tried to do it by myself but was unable to. My Calibre still will not work with this. Still freezes up if I have the Nook plugged into the puter and the Usb Storage turned on.
