I recently purchased an ebook with DRM to read it in my Kobo e-reader, so I downloaded ADE 4.5 but it crashed after page 5. Following instructions on Kobo forums I uninstalled ADE 4.5 and downloaded ADE 3.0. It keeps crashing after page 5, both on my ereader and also in the computer using ADE 3.0. So now I cannot read my ebook at all. Any suggestions? Thanks.
