Please try to deactivate some devices as explained in this KB article:
"Your Language Cloud account has reached the maximum number of registered devices for the current subscription." when trying to activate Trados Studio (sdl.com)

But I am not aware of any other device that I have activated so far, because I do not use any other devices than this. 

Should I deactivate the devise that I am using now to activate the same one?

I recently used only those devices that are attached to the PC that I am using.

I am a little confused about this fact.

Kind regards, 

Tony Yoon

Hi Taegeun Yoon 

Yes, please remove the device you are using now and then try again. If the issue reoccurs, please let us know, so that we can open a case for you.

Kind regards,

In a cloud-based setup with Trados Studio, the term 'device' can refer to more than just your physical hardware like your laptop or PC.  When working with Trados Studio in the cloud, both your installation of Trados Studio and your browser (which you use to access cloud-based features) can be considered 'devices.'  Each of these counts toward your total number of registered devices under your current subscription.  So, even if you are using the same computer, if you access Trados Studio via both the installed software and through your browser, they might each count as a separate device.
