Crystal Reports 2011 with Universe Error

Hi,

     I want to have my crystal report to use the universe as a database connection to retrieve data. But after I drag the fields required to the query, there is an error said "invalid argument provided. details: crystalenterprise14.fw_properties.1: item si_webi was not found in the collection. I do not have problem when i use in webi. Is there any settings required? I am using BO 4.1 SP1. The universe is using a connection to sql server. My crystal report 2011 is installed in a Windows 7 64-bit machine. Thanks in advance.

Thanks

Anil
