Couple of things to keep in mind:
1. If your CIC is still on the factory firmware version (Before March 2010), maps cannot be successfully updated via USB. (The map should show an "i" with a checkbox in the lower left corner)
2. If you retrieved your 1B file with the USB method, it may not "grab" the right part of the persistence file, or may have a corrupt file.
