I have not touched my Litecoin wallet in several years. I had some coins in a Litecoin wallet before 2014. Then in 2014 I upgraded the wallet to the latest version at the time. Immediately after doing that, the new wallet showed a zero balance. I tried to get help at the time and I think something big was going on with Litecoin and I gave up. I just thought I would revisit this because I understand that usually keyfiles are stored somewhere and I just want to check to see if they are still on this computer somewhere and if there is a solution. I have the same computer (Mac). The wallet currently installed showing the zero balance is Litecoin v0.8.7.4-beta.
I have no other information written down or stored off the computer - I know! I was going to do that right after the upgrade. I know, should have done it before!
Thanks for the help!
