private messaging and contacting sellers

[rigga]

Tried to message someone on here through the contact me part of their profile, normally goes straight away and I have a confirmation email in my own inbox to show its sent, recently this didnt happen until two days after I sent it, and I think seeing as I've had no reply I don't think it went through.
Secondly just tried to contact a seller regarding some part's, and it just would not send, just kept highlighting my email as if it was wrong, and wouldn't go through.

Yes same email address, used it many time's before on classified stuff , but it just would not accept it this time, just refused to send and kept the address highlighted in red/pink as if to say it was incorrect.
