So fired up my old faircoin wallet, been a few years, so no coins in it anymore, surprise surprise
Can you check your transaction record from your client?
Can you see any wallet transactions?
Do you have a wallet.dat backup?
My wallet was empty when I fired up the new client from my backup.
On the new client I had to change the name of my backup dat file from
faircoin.dat to
wallet.dat.
After I did the name change, I pasted the newly named backup in the Faircoin folder and my wallet was restored.
