Exception after installing UR-18 on MS CRM 2011 (UR-8)

Hi All,

We are getting the below exception after intalling UR-18 on MS CRM 2011(UR-8).

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Could not load type 'Microsoft.Crm.MapOrgEngine' from assembly 'Microsoft.Crm, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. (G:\MSCRM2011\CRMWeb\web.config line 124)

It would be great if anybody can provide the solution for this.

Thanks
