I have tried other tif and box files as well producing similar errors which 
have a more structured body of text

We provide support only for official process 
https://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract. 

"Font id = -1/0" indicates that is problem with font_properties (see FAQ).
3.02 training is quite old. There were many fixes in recent code (unreleased 
3.04 version), but training on windows is not supported there.
