Missed the zip when posting first time.

The problem is with the name of the depthMapSize channels for the lights.
The string "Map Size" is the name of that channel in each of the lights.
If you replace it with "GetStringRes(1028,29)" (no quotes), then the utility doesn't complain.
Alternatively putting quotes around the name string also cures the problem.

You might also want to use the GetStringRes(1028, ...) forms of the names for some of the other channels.
