Will un-installing both armory and bitcoincore, then re-installing be an easier option?
Not really, need the logs to see what's wrong.
Both logs
armorylog.txt and dbLog.txt
Armory datadir
Depends on your operating system. Assuming Windows, the default location is
C:\Users\*yourusername*\AppData\Roaming\Armory
You have to show hidden folders to reveal AppData.
You can also start Armory in offline mode to extract logs through the menu option.
Once you got the logs, post them on pastebin. If you get the logs from the GUI, you'll only get one file, as it merges the 2 logs into a single one.
