I have tried to authorize my PC with the Adobe ID in order to reed some bought e books - but this has failed, so far.
I get a message saying: "You can only authorize with an Adobe ID that hasn´t been previously used to authorize any other computer or mobile devises. Please try again".
Well! I have several devices that I have used my e-mail address for.......and I am allowed to reed e books on up to 6 different devices......so.....what to do???
