I run armory on an external 2TB hard drive.

....

(WARNING) SDM.pyc:396 - Spawning DB with command:./ArmoryDB.exe --db-type="DB_FULL" --cookie --satoshi-datadir="A:\_Data\_bitcoin-core\blocks" --datadir="C:\Users\lac\AppData\Roaming\Armory\" --dbdir="C:\Users\lac\AppData\Roaming\Armory\databases"

I think your pathing is screwed up, unless A:\ and C:\ refer to your external drive.
