(Rather than getting the SCMS error message, I get a more generic error message when trying to pair.) I noticed that the registry entries cited in the original thread weren't found during a search of my registry with either version installed. Tried running SwitchTosSCMSCheck on top of Toshiba's bluetooth stack versions 3.20 and 4 without effect. Just an FYI, I'm also running into the same problem. Same problem - no change to BT headphone prob
