I just tried it in Track Pane, Console (track and bus strips), in the Inspector strips, in the Clip Inspector and dragging directly onto a clip. All of them worked. Not sure why it's not working on your end.
Just to be thorough:
Open the Browser (press B)
Select the Plug Ins tab
Press the Audio FX button
At the bottom of the plug in list click the + button beside where it says FX Chain to expand the Chain choices
Click the + button beside one of the sub folders (just for this choose Drums)
Now you should be at the bottom of the folder and looking at the actual FX Chains
Click and Drag the Chain that says Automate Me into one of the bins I listed above.
That should do it. Maybe you were trying to drag one of the folders into the bin which doesn't work for obvious reasons.
If it doesn't work I have no idea what could be wrong and I would contact Cake tech support to see what's up.
Cheers.
