Ok, in that case, I'd check the HANA client software version and recommend to update it to the most current release if it isn't already installed.
To check the version, open a command line window and navigate to the folder where you installed the HANA client software to.
In there run
> odbcreg hdbodbc
You should get back something similar to this:
DriverName=hdbodbc
Driver=C:\Program Files\sap\hdbclient\libodbcHDB.dll
Setup=C:\Program Files\sap\hdbclient\libodbcHDB.dll
Version=1.0.50.46111
