Wraptor DCP creation failing on compile

Been trying to create a 2K dcp using the 2K Digital Cinema Flat 24 fps, and the render is consistently failing with the following error:

07/12/2015 03:14:39 AM : Encoding Failed

------------------------------------------------------------

A low-level exception occurred in: Wraptor DCP (Exporter)

Export Error

Error compiling movie.

Unknown error.

------------------------------------------------------------

The target drive has 1.8 TB available, and the source file is a 24fps proRes 422HQ quicktime with 24 bit uncompressed stereo audio.

Suggestions where to start looking? 

Thanks in advance,

Robin Remde
