Error in Cognos Analysis for Excel v10.1.1

[simplyguru]

Hi,                                                                     
                                                                       
when we hit the MORE or ALL link in the panel where the data is pulled 
using the Cognos Analysis for Excel 10.1.1. we are getting the         
following error message.                                               
                                                                       
"The remote server returned an error: (500) Internal Server Error."

i have attached the screen shot for the reference. any help to resolve this would be great.

Thanks,
Guru
