vs 2005 and crystal report configuration error

Hi folks,
I am using vs 2005 and sql server 2005 as backend for my web application. I have also used vs 2005 in built crystal report for reporting. My application is working fine on my coding server but it is not working with my production server which is configured with crystal report 11 and giving me some configuration error.
I am not getting why it is giving me such error. Please help me out…
