Version is 0.6.1.0 for whs 2011. The buglet appears in the add-in and not in the "console" program (when I edit the type/profile there everything is ok).
Here's an example on how the "buglet" shows itself (can't supply an image I'm afraid):
Device Host Name IP Address
Device Profile Status
Sony Bravia TV (2009) 192.168.0.27 192.168.0.27 'ProfileName' is not a parameter....* ACTIVE
*) 'ProfileName' is not a parameter-less method, property or field of type 'Serviio.API.ServiooDevice'.
All devices discovered shows this message as their Device Profile irregardless of what the profiles says it is in the console. My Sony tv correctly displays the profile as being 'Sony Bravia TV (2009)'
