    <p>Hello,</p><p>I executed the sample sent by you by replacing the FarPoint references in your project with the latest version of Spread v3 i.e. 3.0.2010.2005 and I do not encounter any exception at my end by following the steps suggested by you in your first post. I would suggest you to update to the latest version of Spread v3(3.0.2010.2005), and try executing your sample with the same. Please let me know if you still face the same issue.</p><p>Thanks,</p><p>Manpreet Kaur. <br></p>
