Hi
We have developed a console application (C# language) which produce .sdltb file using Sdl.MultiTerm.TMO COM component which is installed with SDL MultiTerm 2017.
but after file creation, in SDL MultiTerm 2017 when I am opening this termbase files, I cannot add a term to it. after clicking "Add New" from upper menu and entering a term in to the textbox and clicking the tick button, this error will show up in a red box:
"One or more errors occurred."
. . . and nothing will add to the termbase.
What is wrong with my Console Application.
here is the heart of the code:
 oMt = new Application();
 oLocalRep = oMt.LocalRepository;
 oLocalRep.Connect("", ""); 
 string definitionFile = ". . ."; // select an appropriate .xdt file name among many files has been created before by "Multiterm Convert" software  int orderId = . . . ;
 Termbase oTb = oLocalRep.Termbases.New(orderId.ToString(), desc, definitionFile, string.Format("{0}.sdltb", orderId));
 string conceptGrpS;

 DataTable d = . . . ;
 for (int i = 0; i < d.Rows.Count; i++)
 {
  var conceptGrp = new Mtf.ConceptGrp();
  conceptGrp.LanguageGrps = new List<Mtf.LanguageGrp>();
  DataRow dr = d.Rows[ i ];
  AddWordInLang(conceptGrp.LanguageGrps, sourceCode, dr["SourceTerm"].ToString());
  AddWordInLang(conceptGrp.LanguageGrps, targetCode, dr["TargetTerm"].ToString());
  conceptGrpS = Serialize(typeof(Mtf.ConceptGrp), conceptGrp);
  oTb.Entries.New(conceptGrpS, true);
 }
 oTb.Close();
 

///////////////////
// in above code , this procedure and class is called:
 private void AddWordInLang(List<Mtf.LanguageGrp> nest, string lang, string term)
 {
  nest.Add(new Mtf.LanguageGrp()
  {
   Language = new Mtf.Language() { Lang = lang, Type = lang },
   TermGrp = new Mtf.TermGrp() { Term = term }
  });
 }
 
   public class Mtf
    {

    }

also the sample of my termbase file is attached:

 used xdt and the final sdltb.zip

 thank you
