When I load ADE 4.5 it reloads books that are already in the library creating duplicates. If these are not immediately deleted from both the library and My Digital Editions they will reload next time the program is accessed causing still more duplicates. It is somewhat annoying to have to do this every time the program is accessed. At the moment it is reloading about 180 books which as far as I can tell were loaded from ACSM files. The ACSM files are no longer on my computer. Has anyone else had this problem and has any idea how to fix it?
