Too many devices are attempting to connect with the same access key." My license has already been activated on 3 machines, and some of the old machines are no longer in use (one was replaced / scrapped / had a hardware failure), so I am unable to deactivate them locally. Could you please help reset / release the existing device activations so that I can activate PSpice for TI on my current machine? My registered email address: 2328652683qq.com I can provide the old MAC addresses or any other information needed for verification via private message. Thank you very much for your assistance.
