can do, send me a PM or host the file somewhere with a link
Your collegue needs to make sure his copy of InDesign CS is updated to 3.0.1 or whatever is the latest version of CS.
I found this info online:
InDesign CS requires the InDesign CS 3.0.1 April 2005 (CS2 Compatibility Update) to open INX files created in InDesign CS2.
InDesign CS may crash if you open an INX file and the correct update isn't installed, or if the InDesign CS2 document that created the INX file contains missing links or problematic third party plug-in data.
InDesign CS may crash when links are broken and Color Management is enabled. If the links are active (that is, not broken) you should be able open INX files in InDesign CS with Color Management enabled.
Good info Bo, the links were certainly not included with the source .inx
