Hi mshooot,

The error you have encountered can occur whenever you have different versions of Telerik Reporting assemblies, due to improper upgrade. Please run the Upgrade Wizard manually to make sure it upgrades your application properly. If the error persists, please check all references manually and make sure they point to the latest version.

Generally if you plan on upgrading all of your projects with the latest version of Telerik Reporting, you no longer need the older versions and you can go ahead and uninstall them in order to avoid such problems. Additionally if you're using web site project, make sure you delete manually older Telerik Reporting assemblies from the bin folder, as they are not affected by the Upgrade Wizard.

All the best,
