How do I call a stored procedure (ASP.net) using the IBM provided OLE DB driver. I'm getting an error message.

I'm trying to call a simple stored procedure that takes an input parm (string), does a look up, and returns an output parm (string).  I'm using ASP.NET (VS 2008) using the 2.0 framework.  I'm calling an IBM DB2 9.1 LUW database running on Windows 64-bit through OLEDB .  Here is the message I keep getting when trying to call this program.

There was an error. IBM OLE DB Provider for DB2 [DB2/NT64] SQL0444N Routine "*FOR_ZONE" (specific name "SQL080717085156720") is implemented with code in library or path "\FTC.LOOKUP_STATE_FOR_ZONE", function "*TE_FOR_ZONE" which cannot be accessed. Reason code: "4". SQLSTATE=42724  

Please help.
