Sorry for the barrage of help requests.  I don't know much about tex but it's possible the tex output from one file I am working on is buggy, as mk4ht refuses to read it.  The .org and .tex files are attached, as is the initial error output of mk4ht oolatex His495Ouline.tex.  This is perhaps the wrong list to be asking on, but I am sort of working from the assumption that there's an issue with the tex code that org produces -- mk4ht seems to work fine with simpler documents.  I';m using a pretty recent org-mode (7.01 from not that long ago). 

Thanks much!
