Your best bet would be to try clearing out some of the junk from the website.

Any idea how to get around this?
Thanks a lot!

# This script is designed to take a wordpress xml export file and split it into some
# number of chunks (2 by default). The number of lines per chunk is determined by counting
# the number of occurences of a particular line, ‘\n’ by default, and breaking up the
# such that each chunk has an equal number occurences of that line. The appropriate header
# and footer is added to each chunk.
