I had just assumed that the temporary wallet address expires?
There is no such thing as "
temporary address", if it came from Armory's "
receive bitcoins tab", that address belongs to your wallet.
If Bitref (
a simple blockexplorer) displays that the address has balance, you have successfully received your bitcoins.
The problem is on your client's side.
Where did you get that client, from
https://btcarmory.com/ or
https://www.bitcoinarmory.com/?
The second one is an outdated source.
