Hi Jesse Herrera,
Thank you for writing.
Most probably, the reason for the RadForm class to not appear is an assembly reference issue. Most likely, the project is still referencing old assemblies from Q3 2007, because you do not uninstall it and now in your GAC there are assemblies from old and new version either.
Please, check the version of assemblies in your project references (right click and select the properties item) and reattach it. If this does not help, make a clean install of the latest version: Uninstall all Telerik RadControls products, clean your GAC, and install Q1 2008 SP1 again.
I hope this helps. If you have other questions, do not hesitate to contact me again.
