armory_nnnnnnnn_.SENT.tx
Okay, so that transaction was previously attempted to send to the network due to the 'SENT' in the name.
Anyways, you can still load it the same way as loading a signed transaction as long as the contents are correct.
it should look like this (
sample from RegTest, do not send):

If you don't want to wait for Armory, you can send it now to the network using any "
push/broadcast service" by copying the RAW Transaction in HEX.
You can get it by following my previous reply until "
load file", but instead of broadcast, click the text in blue: "
Click here for more information about this transaction", then "
Copy Raw Tx (HEX)".
That should be compatible with broadcast services like
https://blockstream.info/tx/push.
Lastly, Armory should be in "
Advanced User" mode or higher for the buttons to appear.
