Problem with ODBC - Data from Korea

Hi, 

i am getting this error trying to create a Schedule refresh procedure in the service:

when i am refreshing the same query from the Desktop or making a "Refresh Now" process there is no problem (the data is refreshed successfully) 

any thoughts? many thanks

This is the Error:
