Tesseract is looking for chi_tra.traineddata instead of kor.traineddata

[fjay69]

I try to construst TesseractEngine for Korean:
var engine = new TesseractEngine(@"C:\VS\Tess\tessdata", "kor", EngineMode.Default)
and get these errors:

Error opening data file chi_tra.traineddata
Failed loading language 'chi_tra'
Empty page!!
Empty page!!

Am I doing something wrong?
