Firstly, when you started Armory, did you get a cmd window? If you did, don't close it, that's ArmoryDB and it must be running.

Secondly, to set custom datadirs, Bitcoin Core needs to have --datadir. Armory needs to have --datadir for its own data directory which is not the same as Bitcoin Core's. In order to tell it where Bitcoin Core's datadir is, you need to use --satoshi-datadir.

If you did not delete the databases directory inside Armory's datadir at some point already, I suggest that you stop Armory and do that now. Even if you did, I think you should do that again to force a rebuild and rescan. The new Armory databases build much faster than the old ones and are much smaller.

Whilst ArmoryDB is building the db again, watch that there are no errors being reported in the cmd window (which the dbLog.txt mirrors). If there are, please report back with the full dbLog.txt again. Also check that it actually scans all the block files and all of the blocks.
