hmm, do you have the Remote Buddy kernel extension installed?

If so, please try without the Remote Buddy kernel extension 
installed. Remote Buddy installs the Apple® Remote Emulation through 
the kernel extension on start, and removes it on exit. It's not 
active all of the time.

You can easily remove, load or just testdrive the kernel extension 
through the Setup Wizard, which you can also reach via the menu item 
on top of the screen. If removal fails, it's usually just unloading 
that fails because some app on the system still holds a reference to 
it. A reboot does then fix the problem.

Thanks for wishing me luck :-)

Best regards, 
Felix
