Error in Crystal report when selecting OPOR

Hi,

I'm using Crystal Report 8.5 in formatting reports in SAP and when i select OPOR and POR1 tables i received an error message like this:

Unicode data in a Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier.

Can somebody help me solve this?

Thanks very much.
