Hi schase,

This error may indicate that the file was to large to upload and would depend on the server upload limit.
It might be set as low as 2Meg if that is the case you might want to compile just one section at a time to see if things work as as expected.
Also check that these are writable 777:
administrator/components/com_export_content/
img/...
administrator/components/com_export_content/
zip/...
administrator/components/com_export_content/
new_version/...
And that you have the correct versions of Export Content installed:
Export Content version 1.0.0 is for Mambo
Export Content version 1.7.0 is for Joomla 1.0+
Export Content version 2.0.0 is for Joomla 1.5+ (legacy mode)
