I am really thinking about mentoring as a viable business.
1- do you have coins on your old wallet? if yes, can you see your coins in your old wallet?
2- what it's the name of your old wallet (the software)?
if you want to move your coins from the old wallet to the new one, you may just get a new address from the new wallet and send your coins from the old wallet (you may be ask for your passphrase, in order to do that).
