The profile exists, they're a new registration but the account hasn't gone through the approval process so the number of PMs they're allowed to have is severely limited (this is a result of people registering and sending mass spam PMs before their accounts were approved).
So you can either wait until their account is approved which might be a few days, or if you want I can send them your contact information directly so they can get a hold of you if they want. If you want me to do that PM me what you want me to send them and I can email it to them.
Uncertainty is an uncomfortable position.
But certainty is an absurd one.
