Awesome work Cathy. I watched the full video, figured I'd post some spoilers for others about to sit down to the same.

(It's a ~20min video, so grab a coffee! Corrected link: http://blip.tv/file/1757864 )

UC team, note there's a bug shows up at 11'00", where UC ignores the selected SKU and assigns the file download "SKU: Any". Cathy tries a couple of different methods to set SKU: 10001, but neither works.

Cathy, I can see why your fix was required if Paypal wasn't updating the order quickly enough. However, when I followed through your progress, I duplicated your module install and then copied the debugging method of adding order comments as each Conditional Action ran, and then (before adding the additional rule you added) I tested an order.

For the first time, IT WORKED. YAY!

So either (1) enabling Token Actions fixed the issue for me (in which case, uc_file should depend on token_actions) or (2) activating the debug messages nudged UC into triggering the download.

I'll test further and see ... good work, thanks for making the video!
