Has this happened to anyone else?

[Rustymini]

About three hours ago I had a sale (while I was out) my first this year so I was quite pleased about it. I've just sent an invoice, however when I pressed the send button I had a message that the buyer was "no longer an active user".
Has this happened to anyone else or am I being the victim of something?
Thanks for reading this - it really has got me stumped.

See what I said in the other thread. i.e. contact support.

I've just checked the buyers ID. They only joined Ebid 4 minutes before placing the order with me.
Thanks for the advice Oldandintheway - I'll do that.
