Error 51133, F5 registration key is not compatible with the detected platform - This platform, "Z100", cannot be activated with this regist

This is error generated purposely. F5 never wanted to gives a trial version and this error message shows up every copy I tried. F5 support team, can do nothing and won't do nothing. If you buy a used gear from ebay you cannot use it, without paid support contract key, this never happens with any other vendors and this is a gauging scheme.
