I originally followed the forum instructions to show the blackberry maps program and all was fine. Then I updated my 8800 to remove some themes and save some space as per another post and my maps disappeared again. I checked for the existence of a vendor.xml file and ensured that the lbs.alx, platform.alx, and blackberry.alx files were the ones I downloaded from the forum, but my bb maps is still hidden. Which step did I leave out?
