Has anyone else had problems loading epubs on an old eink reader? I have an old Bebook, I love it coz the battery, even after all this time, still stays good for at least a week, but about half of the books I buy (with DRM or without) won't open on it. Is there something funny happening with newer formatting that stops them being compatible with older ereaders? (and I have the last available update for the Bebook)

Thanks for any thoughts
