Parse Error - Unable to retrieve Dita Profile

Hi All,

I am new to AEM Guides and tried my hand at importing an existing DITA project from https://github.com/DITAWriter/pilot_training_mitchell_bomber

This is a DITA-fied version of the Pilot Training Manual for the Mitchell Bomber B-25

I installed the package - com.adobe.fmdita.uuid-6.5-4.6.1.5886.zip

I was unable to install the package com.adobe.fmdita.uuid-6.5-SP due to dependency com.adobe.fmdita:com.adobe.fmdita.uuid-6.5:5.0.0.211

I created a folder in my DAM project and dumped .dita files from the above repo in it. 

When I tried to access the same in Guides editor window I get the below - 

If I try to go into “Preview” mode I get the “Loading preview...” overlay which doesn’t go away - 
 

Can anyone help point what am I doing wrong here?

Thanks,

Nagesh
