You'll need to post your logs. Specifically, the armorylog.txt and dbLog.txt from the Armory data directory. (If you're on Windows, this is in the "%appdata%\Armory" directory.
Don't post the logs here (they probably won't fit in the max message size)... copy the contents of the log files to
https://pastebin.com/ and post a link to the pastebin records here.
Also, have you confirmed that your bitcoind/Bitcoin Core node is actually running and syncing properly?
