Good evening. I purchased an ebook in .acsm file but it won't open in Adobe Digital Editions. It will tell me: E_AUTH_BAD_DEVICE_KEY_OR_PKCS12. I know my comuter is authorised, I have done this so many times and never had this problem. The book e-shop support advised me to de-authorise my device and authorise it back again. But there goes another problem: a message sayig "Unable to erase authorisation. Try again later." Please help! Martina
Have something to add?
