OK, I took the plunge and upgraded to org-8.0 and tried the new exporter.

The HTML export works fine! However, I'm having trouble exporting to PDF
via LaTeX.

I use a LaTeX custom class which I hired someone to create for me, which I
load as a preference file latex.el: http://pastebin.com/SW0Xqe2h
(the custom class is called ilija).

It worked perfectly up to org 7.9.4.

But now my PDF documents are coming out all garbled:

Here's the Org PDF LaTeX Output:

I don't really know how to interpret all those errors, except that I do
notice this:

Package hyperref Error: Wrong driver option `xetex',
(hyperref)                because XeTeX is not detected.

Again, it was working before I upgraded to 8.0.2, and it still works
perfectly when I load org-7.9.4 instead of org-8.0.2.

Reference: OSX 10.8.3, Aquamacs 2.4 / Emacs 23.3.50.1 / org-8.0.2.

Any ideas? Thanks in advance!

Best,
Peter
