I downloaded the latest build. I notice the change in CuteWebUI.AjaxUploader.dll timestamp. I removed the old .dll from the bin and replaced it with the one from the new build and added as the reference in the studio, compiled it and tried in a new browser. It still did not work. 

 

The files were uploaded to C:\Documents and Settings\CDNMSC3\ASPNET\Local Settings\Temp\AjaxUploaderTemp

Thanks.
