Lost change address question, yes I have backups.

[WildFire.ca]

I have lost half a coin in a change address due to me not having my settings correct. It's not a lot but it is enough I would like to recover it. I have Armory encrypted and unencrypted backups, paper wallets, plus I have the Mnemonic info. Is it possible to recover this lost half a coin? If so how do I go about doing this. I clicked on the addresses used number and increased it to 1000 and then checked all the change addresses (15 of them) on Blockchain.info and there is no coins in any of the addresses. On a side note I am having problems getting bitcoin.qt to sync but that is a problem for another section. But this also means that right now Armory is not synced either while I am trying to recover the change address. Also I am doing this with the wallet still encrypted. I can decrypt it but I just don't like putting my passphrase in unless absolutely necessary.
Thanks for any help you can provide.

Click on the Receive Bitcoins button a couple times and check those addresses. Once you fix your Bitcoin Core and it is fully synced, have Armory rescan its databases and that should find the addresses with the Bitcoin.

The only thing I forgot to mention, and probably the most important is that the backups were made before the change address was created.

35 weeks left to synchronize.....

Doesn't matter, your wallet comes with the data to reproduce any addresses on its chain.

Sweet, that is what I had thought would happen, but was unsure. Thank you guys for your help. Core crashed during the night, so there are still 25 weeks left, then I am going to leave it running for good.
