[oXygen-user] Transformation scenario error message?

I have a Transformation Scenario that fails. This scenario uses a customization layer, and a FOP configuration file for embedding fonts. I've checked and double checked all my paths, and they are accurate: the FOP configuration file (I used the browser to select the file), the font metrics and TTF locations, etc. The only error I get when it fails is below: Description: The process 'FOP' ended with code : 2 The error was : [ERROR] null Is there any way to get more output? Thanks.
