At any time did you use HRDLog.net? There is a choice in the configuration to automatically upload to HRDLog if you did you can down load your log from there. Also did you have your log setup to automatically back-up your log on another Drive? If so your log is there (You do back-up your log right?). Also if you upload to LOTW you can use the the K1MU LOTW Query page to download all of your QSO's and QSL's here www.rickmurphy.net/lotwquery.htm
. There is a way to save the eqsl file as a .ADI file but I am fuzzy on that since I have not done it in quite awhile. I do feel your pain I have had to do this a few times befor I started backing up to 2 different drive one being in the Cloud so if I ever had the house burn down I will never have to try to rebuild my log the hard way. BTW HRD is the best program I ever found for logging period.
