Hi, I've uninstalled the Nöerd Multiple File Upload 1.1 and installed Gecko Uploadify in it's place.

Now all my .swf content is not showing!!

And when I try to add media items by clicking a media subfolder I get a YSD:

The control with ID 'uploadFiles' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: The control with ID 'uploadFiles' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

Source Error:

Does anyone have any insight into what I might do to correct the problem (I have tried uninstalling and installing again).

Best regards,
