Hi,
What CRM version have you installed? If it is 64 bit then please make sure that the two .dll files in the /bin directory of the portal site are 64bit versions of Microsoft.Crm.Sdk.dll
and Microsoft.Crm.SdkTypeProxy.dll and replace the 32bit ones in the /bin directory on the portal site. You can get the 64 bit version of files form CRM Sdk folder.
You may also refer to the URL for more information: http://usingmscrm.blogspot.com/2010/02/microsoft-dynamic-crm-4-event.html
Please mark as answer if you find the reply useful.
Thank You,
