I've also had the issue with the "No Sender" message when I send a picture. I think it might be a hiccup from the program since it was ported over. I've done the Regedits that Mr.Hawaii posted a few pages back and still get the No Sender message.
Here is the registry edits I was talking about!!!!
Hey guys I posted this in the Diamond forum of this thread. If anyone uses this registry edit can you please report back if it helps/hurts anything? I want to see if my results are consistent. Thanks.
HKLM/Software/Arcsoft/Arcsoft MMS UA/Config/mm1/WspHeader/
Values 'User-Agent' and 'x-wap-profile'
