Accordion from XML Error

I downloaded the DHTMLX Suite and im getting and error when i want to load an accordion from a xml.
The sample of the DHTMLX page is working ok but i tested the sample that comes in the suite and i got the same error.

Execute E:\DHTMLX\dhtmlxAccordion\samples\01_init
Load from XML

The sample is 08_init_from_xml


What shtmlx version? 3.5?
