I have also remembered I was getting an error that stated something like stopblockingthread error on my PC, that's when the DB.exe would crash in Armory.

1. You should update to Armory 0.96.5:
https://github.com/goatpig/BitcoinArmory/releases/tag/v0.96.52. I would still like to see a log file, would help with the debugging
3. Your best path forward is to empty your "databases" folder. You'll find it in the Armory datadir then start Armory. On Windows, the default path is:
"C:\Users\*accountname*\AppData\Roaming\Armory\databases"
