Error while verifying database on crystal report

I am using crystal report 7 to connect with stored proc on a sybase 11 server. I am getting the following error when tried to refresh the database.
ODBC error:[intersolv][odbc sql server driver]optional feature not implemented. Error in parameter 1.
How can this be resolved? :confused: Stored proc is fine and it runs perfectly when executed. But when refreshed thru the crystal report, I get the error. :( The changes made on the database are not reflected because of this error. :oFor SQL Server database, an error file is created at the location

C:\WINDOWS\Crystal\SQLSvr.err

This file gives the reason for the errors occuring in the report. Check if such a file is created for Sybase. Prob this would help you.
