Dear Dave,
Have you tried to import the backup file to the server directly?
To do that, please install the server first, then place the file parameters.txt to server main folder and put there the backup's name.
Make sure parameters.txt has exactly this name (lower case letters), and must be plain text, with absolutely no other characters inside.
Run the service, you should see in the log that the backup is being imported, after it's done, the service should close.
Make sure you remove the backup's name from the parameters.txt file before you run the service.
Can you connect to server? Do you have any messages?
