WMP Track Information - missing from registry

[Mordasius]

I've been using the Song Signature plugin to get WMP track information from the registry but now the HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\CurrentMetadata key is missing. I'd had a few problems with it not updating before but the CurrentMetadata key disappeared from the registry completely after installing the Windows 7 x64 SP1 update.

Is it just me or has everyone else lost the CurrentMetadata key since installing the SP1 update?

UPDATE: Duhh... The problem was that I hadn't reinstalled the Song Signature plugin!!! Works fine now.
