Error getting License. License Server Communication Problem: E_GOOGLE_DEVICE_LIMIT_REACHED

[paulinec5889037]

Hi,

I keep on getting this whenever I try to open a .acsm file in my Digital Editions:

Error getting License. License Server Communication Problem:

E_GOOGLE_DEVICE_LIMIT_REACHED

The .acsm file  was previously opened in another Mac with its own Digital Editions, authorized under a User ID. But I have already deauthorized that Mac and I have even deleted the Digital Editions program in there. Still won't open in this other Mac with a different Digital Editions. Please help.

Thanks,

Pauline
