vault001.vlt is missing

After I had to reinstall my computer I also reinstalled Maintype 11. I have a backup and tried to use it, but got an error message:
Vault file “vault001.vlt” is missing!
In my backup folders there is only a vault000.vlt file. Trying FmsConfig did not help - the backup can’t be restored.
Is there something I can do or is my backup corrupt and all that was in it lost?
Thanks for your help!

The best way to make and restore backups is explained here:

If that doesn’t help, then a full uninstall and a reinstall will allow you to use MainType, but then you have to start all over with groups, tags, and ratings.

Thank you. That’s exactly what I did, but it didn’t work.
Seems i am out of luck. :frowning:
