Licence (Integration Kit for SAP )

Hello,

I have downloaded the "BusinessObjects XI 3.0 Integration Kit for SAP" from the link https://boc.sdn.sap.com/node/18962 . I use it with Crystal Report 2008 and it works fine. Now, I want to buy the licence but someone told me I can't, I need to buy BO Edge Series or BO Enterprise and I will get Integration Kit for free.

Could you tell me if I can buy only One Licence of "BusinessObjects XI 3.0 Integration Kit for SAP" and use it with Crystal Report 2008? If so, could you tell me where and the cost to get it.

Thanks

Cris
