Hi Youngke,

We will need more information regarding your issue - what is your current setup, what is the structure of the report you get the exception for and any other related data that will help us identify the culprit faster and advise you more accordingly.

Hi IvanY

Thanks for the reply.  I was able to solve the problem by re-installing the latest version of Telerik Report and NOT specify the Telerik Report version to include in my ASPX page.

I think the problem was just ASPX looking for an older version of Telerik Report after my computer updating to a newer version.
