You want to use the mainnet. Make sure that when you run Bitcoin Core and Armory that you do not have the -testnet option set anywhere in their startup commands. Make sure that you are using the normal Bitcoin Core shortcut, not the testnet shortcut. The normal shortcut has an orange icon, the testnet one is green.
Sorry to go on radio silence but I'm trying to readdress this problem now.
I found the transacation on Bitcoin Block Explorer so the amount should be in my Armory wallet. But I just haven't been able to connect Armory. I deleted Bitcoin Core previously and I am running the full node now.
Is it worthwhile to uninstall Armory and then reinstall? As long as I record my wallet address, ID, and passphrase from the current Armory wallet, can I upload that wallet again to Armory?
Is there an easier way to recover the amount? Maybe login to another program? Can I screen share with you? I'm not sure how I got caught up with the testnet details, but this is going over my head technically. Thanks in advance
