CRM integration problems

Hi,

I've successfully established an SSO with my CRM system from the portal. I've implemented the business package for including the channel management functions as well. I'm able to access some iviews as well. But sometimes I get an error http:// : /sap/bsp/sap/crm_bsp_frame/ mainDH.do not found or http:// : /sap/bsp/sap/crm_bsp_frame/ entry.do not found. Please guide me on how to progress further.

Thanks in advance,

Pinac
