If you are having stability issues, you want to use this:
https://github.com/goatpig/BitcoinArmory/releases/tag/v0.96.0.3-testingBootstrap the DB like this:
1) Delete the content of C:\Users\XXXXXX\AppData\Roaming\Armory\databases. Don't delete the folder, the DB won't create it for you, just empty its content
2) Don't run Bitcoin at all. Open your command line prompt (type cmd in the search bar), cd to the Armory binary folder, and type ArmoryDB.exe in there. This will run the DB on its own. Let it build. Once it is done, it should tell you something like "Enabling zero conf parsing".
3) With the DB still running and the build phase over, start ArmoryQt. This will send the DB in its scan phase.
4) Once that's done you should be done with the hard part. You can shut all that stuff down, start your node and let it catch up, then start Armory the regular way.
