Submit via Email as an attached PDF - not working

Alrighty, I'm in LiveCycle Designer v 8.05.etc

I've created two forms that I would like to have filled out and returned via email aspdf's. The 'Email Submit' button only seems to send xml files.

So I made a 'Submit' button instead, and it works just fine in Acrobat 8 professional, but not at all in Acrobat Reader.

What gives?
Is that a limitation of reader or am I missing something?

Thanks in advance,
