can you provide some more details what you mean by that? does it show an error message? if so what is the error?
when i open the page in Dreamweaver, it gives an error that there are spry elements being validated that no longer exist, you should allow for the lines validating elements that no longer exist to be removed.
also try deleting the webassist/email/mail_php.php file, then editing the UE wizard to have it regenerated
