Hi yes it is going but it still doesnt show idk why

Hello,
i created a wallet when i was in offline mode and also backed it up in offline mode.I made a transaction to that wallet in offline mode,so I never saw the transaction in the armory application.I had to reinstall armory because it didnt connect and with it, my wallet.I connected when I reinstalled it and I restored my wallet.I noticed that it changed adresses and my transaction insn't there.I am sure i sent it to the right wallet, i even still have the receipt.
Why would it just change adresses and not adapt the transactions made from the "old" wallet when all transactions are publicly in the Blockchain???
Please help its about a lot of money.

Have a nice day y'all
