LaTeX file compiles on two computers but not on the third

Question

I have tried to troubleshoot a problem for several days and cannot solve it.

I have a LaTeX document that compiles on two computers but not on a third computer. (Other documents have compiled fine on the third computer, which is relatively new.) All three computers have the MikTeX 2.9 distribution that are all up to date, all use emacs 24.3.1, AUCTeX 11.86, and Windows 7. I have set MikTeX to download packages on the fly so I believe that I have identical packages downloaded. My master document brings in three files via \include. I am reading the files from a portable HD into all three computers. EDIT: Put differently, I am compiling the files on all three computers from files that reside on a single portable HD that I am moving to each computer.

I cannot figure why the document does not compile on the third computer. I believe the problem relates to either the table of contents or section headings of the document because the .toc file is empty (size = 0) after compiling on this computer.

The error message is:

ERROR: Missing control sequence inserted.

This is probably caused by a \newcommand, \renewcommand, \newlength,
or \newsavebox > command whose first argument is not a command name.

The reference to Chapter 14 in the error message is one of the three files brought in via \include.

I tried going through the log file and see some potential problems but I cannot interpret them. Attached is the log file and the issues I observe begin around line 1295. EDIT: This portion of the log is at the bottom.

I believe the issue is probably some kind of TeX installation problem. I hope someone can point me in the right direction because I am stuck.
