Get Critical Error Unknown while debugging XmlParserScript.mq5 from XmlParser library

 

I am getting a Unknown Critical error on line 14 while single stepping through XmlParserScript.mq5 in MetaEditor. 
why? How to fix?

string res=xmldoc.SetXml(xml);

Gets Critical error on line 145 of XmlParser,mqh call GetCode in XmlParser.dll which was copied to Libraries folder as instructed.

GetCode(xml,s);

What is wrong with the XmlParser.dll?

The error message mentioned something about (EURUSD,H1).

I am currently running XAUUSD, M15. Is that the problem? Is the XmlParser.dll somehow sensitive to this?

See attach mqh file.
