Well, thank you very much for your tip (and all the replies)..it did actually help, and yet not I'm afraid. Moving them to another folder did make them not visible in Central, but it has apparently not removed them from it since I'm still getting the message:
You have reached the maximum limit for adding devices
You have reached the maximum limit to add devices. Please add additional subscription keys to increase this limit
It boggles the mind how a company can make a system that allows you to add devices but not to remove them, and then also makes that system not allow you to add more devices than you have subscriptions (because, yes unsubscribing did not help get rid of that message either - I am using 160 of 173 available - which is why I ended up here in the first place).
Anyway, my boss managed to find someone who says he can remove them, otherwise I'll open that TAC case as per the other reply.
Thanks.

If you have access to your Activate account, then create a new folder (Say "Old Devices") and move the device in question to it.
If the device is in the Athena folder (or sometimes in the root folder), it will still show up in Central. Central should be only using the Athena folders.

Hi.
I have activate, and I see the devices I want to remove from central in activate, but I don't see any option anywhere to remove the device from central...or at all for that matter..

If you have access to Aruba Activate (activate.arubanetworks.com), you can remove it from there.
In all other cases, please contact Aruba Support (contact details in my signature) to have the APs removed from Activate and Central.
