trasfer books to e-reader

Hello, I have re-installed windows 7 professional and I have installed again ADE 4.5 (I had 3 before), to use with overdrive and my public (U.K) library. When I try to transfer books to my Kobo e-reader I have the following issues: No permission to copy this book and when I open file and paermission I recieve this: The document is licensed for a different user account. Thanks
