Error "e_google_device_limit_reached"

Hello community, I just bought a book from Google Books and I want to read it on my pc through Adobe Digital Editions, but when I want to open it the program shows me that error.

Could you help me solve it? I have ADE 4.5.11 installed and it runs on Windows 8.1 (64 bits). I just formatted my computer, so everything is up to date and working optimally. I tried deleting the authorization and re-generating it, but it didn't work.
I also tried deleting the "Adept" entry in the Windows registry, but it didn't work either. I don't know what to do anymore. Thank you very much in advance!!
