WHY CAN'T I AUTHORIZE TWO COMPUTERS WITH ONE 1 ADOBE ID?

[almilaakdag]

I KNOW THIS QUESTION HAS BEEN ASKED BEFORE (5 YEARS AGO?) BUT NO ANSWER DID COME. i AM ASKED TO AUTHORIZE SO THAT I CAN TRANSFER DRM PROTECTED FILES BETWEEN MY COMPUTERS AND OTHER DEVICES, AND THE ERROR MESSAGE SAYS THAT I CANNOT USE THE SAME ADOBE ID ON THE SECOND COMPUTER? WTF????
