There is reference to a file...
var filePath = @"C:\Users\Duane\Desktop\ParseErrors\20160628_142635469_b94dde77-857a-4881-8915-6814809c5442.HL7";
...used in...
NHapi.NUnit.Parser.PipeParserV26Tests and NHapi.NUnit.Parser.LegacyPipeParserV26Tests
Any chance you still have this file? If so, can you attach it and i'll add it into the project and update the tests.
