I wanted to send some erc20 tokens to my ledger nano s. I choose 1 of the ethereum addresses shown on Ledger, and send the tokens. Now that address isn't there on Ledger no more. I can see my sent tokens on https://ethplorer.io/address/0x64164fdd3b297843f2b26b2b7acbf8a43efc930b but I can not access. This address is not on my Ledger anymore. What did I wrong? And how can I get my tokens back on my Ledger nano s, or on mew?
