Armory said it's fully synced, but in the bottom right corner there are green letters that say: "Connected 304097 blocks"
If this is the problem and I need to get to 400k something, how to do that on Armory? And why does it say it's fully synced atm?
Indeed, if you are at block 304097 (while the latest is currently 477579), then you are not sync'ed up, and Armory can't see that transaction and your balance.
I do not know how to fix your issue, though, just pointing you towards what needs to be fixed.
