Yesterday I read this page (http://www.telerik.com/help/aspnet-ajax/troubleshooting.html), I tried adding permision to Telerik.Web.UI.WebResource.axd, others things related to the exception (sys is udefined and ajax load) but It still not working.
It's really very strange because I just changed the Telerik.Web.UI.dll.
When I view the source's page and I open the link to Telerik.Web.UI.WebReference.axd (http://localhost:3022/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=radscriptmanager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aes-ES%3afab31106-1bd6-4491-9a14-59e0fc4a7081%3aea597d4b%3ab25378d2%3btelerik.web.ui%3aes-ES%3ad7b88a55-4248-43ee-a9ed-d9058fd97467%3a6c89d69d%3a678692ff%3bTelerik.Web.UI%2c+Version%3d2010.3.1317.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aes-ES%3ad7b88a55-4248-43ee-a9ed-d9058fd97467%3a16e4e7cd%3a86526ba7%3a874f8ea2%3af7645509%3aed16cbdc%3a58366029%3a24ee1bba%3af46195d3%3a1e771326%3aaa288e2d%3a19620875%3a490a9d4e%3abd8f85e4)
I'm getting this exception:

Thank you very much!
