Have you tried the following?

1): Start "ArmoryQt.exe".
2): Go to "Help">"Clear All Unconfirmed".
3): Close "ArmoryQt.exe".
4): Open your file explorer and go to "%APPDATA%/Bitcoin" and delete "mempool.dat".
5): Restart "ArmoryQt.exe" and retry spending your tx.

By the way your tx id is either invalid or not in blockchain.info's mempool anymore. So it is very likely if you follow the stepts above to respend it.
Have you also upgraded your bitcoin core node? The newest version is 0.14.2 and required for the new segwit tx.

This fee is for the current state way too high. Please check https://bitcoinfees.21.co for the current fee. I recommend 60 sat./byte for a confirmation within about one hour.
