I just bought a i62 HD and I tried loading over two drm-ed books and one non-drm with Adobe digital edition. The non-drm works fine but the DRM-ones don't. I can open them but they just register as one blank page. They look okay if you open the Boox in Adobe digital edition and I tried deleting and reloading them. I also tried using Coolreader instead of FBreader but there was no difference.
