I downloaded and installed the new version of all the Telerik controls. I am in a project that I've been working on for awhile and some of my design pages will not load or when I run/test the program, it doesn't work because now some "object references are not set to an instance of an object." When I open a design page, I get errors like this (and I can't see teh design page at all): "No such property registered: IsPressed, Telerik.WinControls.UI.RadButtonItem" or "No such property registered: NumberOfColors, Telerik.WinControls.UI.LightVisualElement" or just "Object reference not set to an instance of an object" Is there something else I need to do besides just installing the new version of the Telerik controls?
