Backups can be a little tricky you’re best to follow the wiki that @MnM posted. simply replacing files can cause corruption especially going from 1.4.2 to 1.5
Im trying to backup on 1.4.2 I delete the Bisq folder inside the roaming and replace with the backup file?? I dont have the directory of the version that was running only the backup file
I don’t know, having a full backup is the best way to backup, changing specific directories is a risky method that should only be done under your own risk or if a dev requires it.
Don’t you have a full backup or the seed available?
If you don’t, you can go to Keybase and ask for support there, I don’t think that paying 200USD will be necessary.
