Hi, Way back in 2014 or so I had coins in a Litecoin-QT wallet on this mac. Then I upgraded the Litecoin-QT and the coins were gone - zero. I tried to figure it out back then but could not fix it. I never got around to writing anything down or backing up (I know).
Just wondering if by default the app install would have replaced the wallet.dat or if there is any chance I can still recover my coins. I currently have v0.8.7.4-beta on the mac.
Thanks for the help!
