What happens if we can't do the upgrade? Or is this just for mining pools? My wallet is an original and I am very uneducated as to how to upgrade
You literally just download/run the V.1.4 version of the wallet and thats it. I just did it myself the other day after asking above, and it was that simple. I backed up my wallet and such incase something happened, but it was 100% smooth/easy.
