Hello!
I have the same problem
Please help me.

I use Armory 0.96.3.992 and Bitcoin Core 0.15.1
I have made paper backup

01/19/2018 23:46 I sent 0.00745953 BTC to my Armory


But I had made mistake before. I used armory offline and created request to receive bitcoins early than bitcoin core have been installed.

After that I've downloaded all blockchain via bitcoin core, but unfortunately it's seems no money in my wallet.

This is blockchain transaction https://blockchain.info/ru/address/1FvHsnwRvrN8uxjoFyFT4oS9nQwsTPqMpg
