Repository Import Failed

I was trying to import LANG_HCOHBAECC.tgz DU in my HANA system but was unable to do. Got the Following error :

Repository: import failed;Import::import(): wrong archive type ET_LANGUAGE_TRANSPORT, you have to use importLanguage() to import this

System Details : Using SPS09

Help me out.

Thanks and Regards,
