Help! I have too many devices registered and want to delete them because they don't exist anymore

Hello there,

I have an issue that I have reset my devices that used AMP Standard Edition over some timeframe and now they still show up as 7/5 devices used on my key. I want to remove them because they are all the two same devices I have always used and are just overwritten OS.

How can I do that?

Also I would be interested what my Dev Edition I have on top of my Standard Edition allows me since there is not much documentation online.

Thanks in advance,

best regards, LCM
