Having major issue trying to migrate Eudora to new WIN 10 boot drive. Copied over all needed Eudora directories/subdirectories/files from old boot drive to new drive and MyMail Data folder as well with same file path as old Eudora setup. Ran compatibility correction on Eudora.exe and when it starts I have absolutely nothing there other than what looks like a fresh installed screen. I have over 7 years worth of historical documentation, etc. for a local non-profit in my old email boxes that I can't afford to lose. Have also tried to retrieve from external backup and get same thing. Eudora import feature doesn't let it import from itself on another drive. Anyone out there who can talk me through how to correct this problem?
