I am using 0.96.5, and bt core 18. Armory shows block 496893.
More than 688,000 block have been mined till now. Therefore, Armory doesn't have access to the full blockchain and that's why your transactions are not shown.
Open bitcoin core and check how many blocks have been downloaded. If bitcoin core is also showing 496893 blocks, it means that it hasn't downloaded the full blockchain and you should let it fully synced.
Do you have enough space for storing the blockchain?
