I've got the error specified in the title when loading  with RegisterEmbeddedXmlFile method.

I'm using XP with Turkish language.

I've noticed that only "E" and "I" were  capital  in Message_Languages.XML file.

I think when fields are changed  back to the small case. "I" becomes "ı" in Turkish.

If youa re missing this column, make sure that it exists within the MessageItems table in StrataFrame (it should).  When you re-export the XML files, does the XML document look correct before you place it into the project itself?
