one issue i see that may be causing the problem is that the text fields in your form do not have a value attribute.
<input name="Name" type="text" class="formElementBg" id="Name" />
I have seen on a few servers recently where form elements are not included in the post array when filled out if there is no value attribute.
try adding value="" to the text boxes:
<input name="Name" type="text" class="formElementBg" id="Name" value="" />
The sticky post regarding UE3 is just to let UE3 owners know that an update is available.
