Sent Bitcoins to an expired address - how do I get back? I sent bitcoins to my CampBX address, and I was unaware that addresses expired, and it had.  So I sent them, they were taken out of my account, and now they are gone...

How do I get them back?

Bitchain says they were sent - but they are not in either account:

Any help would be greatly appreciated.

Thank you!
From Camp BX:

"Do not use this address after the expiry date, as your Bitcoin transfers will not be credited to your account. If you mistakenly make a deposit to an expired address, our system administrator has to expend several hours to track it down. We have to bill these hours out to customer if they wish to recover a lost deposit."
