I turned the subject field off in the settings.. Prior to attempting to do message. So we only have the body line to type in.
I had assumed the send button wasn't highlighted because it's saying the contact isn't registered with iMessage even though we've both filled in all fields and can access and downloads from the apps program ..as a way to confirm our apple Id is valid.
Appreciate the help any other suggestions to try?
Thanks

Oh well, it was worth mentioning it, just in case; though as I read back though the thread (I was in a hurry the first time) I see it was already covered.
The only other things I can think of you've probably also tried.
In Settings > Messages > Receive At, make sure the email address you are trying to use is there, and correct. You can try removing and adding it again. (you can only remove the first address if you have a second one) You could also try alternate email addresses, if you have any. In my experience it will reject email addresses if they won't work; for instance it rejects my yahoo address and gives me a an error message.
It probably wouldn't hurt to make sure the Caller ID matches the email you intent to receive messages at. It tends to confuse things if Messages sends messages back as someone other than who you sent it to.
That's all I've got. Good luck.
