Find the XML in the below directory:

\\arm-proclaim\Prodisk\Proclaim\imports\GLEMISImportFTP\Processed

if there is an ampersand (&) then find the xml file, edit in notepad++, and change it to:
&

This will fix the problem - cut and paste the xml file to the below directory. System will then successfully import.

\\bt-task-03\c$\EmissionsFTPUploads\LeadImport
