Testing aidave's theory turned out to be correct: the problem is that Kabikaboo is attempting to auto-load a file that does not exist--e.g., a document was created in Kabikaboo, Kabikaboo was closed, and then the document was moved/deleted. When Kabikaboo starts again, it attempts to autoload.
Temporary fix is to set "autoopen" in C:\Documents and Settings\Your Name\.kabikaboo\settings.txt to False
