I am having a problem getting all of my NOOKbooks to transfer to my PE. I still have the 1.6 OS and have not tried loading/upgrading to 2.2. I have been sucessful in getting some of the Nookbooks to work but others do not. Probably has something to do with the DRMs, but I can't figure it out. I have loaded Adobe Digital on my PC and have the books there, but they will not transfer to the PE. Any ideas would be appreciated.
