Sorry for the delay in responding. Yesterday was one of those days.
You can do this pretty easily, as you guessed, using the backup files. Make a safe copy of the backup files and the best way to move them is with a USB Flash drive.
From the YuleLog Help pages.
How do I move my data to a new computer?
Windows (95 - XP)
First start YuleLog on the old computer Click on the Save Backup Data Files buttons. This will create three files named Backup1, Backup2, and Backup3. These files will be saved in the YuleLog2 folder which should be in the Program Files folder on your C drive. Copy these files to a floppy or to a USB Flash drive. On your new computer, install YuleLog, using your newest CD, as if it were a first time installation. When ever it asks, tell the installer that this is new installation. Then copy the backup files from the floppy or USB Flash drive to the YuleLog2 folder which again should be in the Program Files folder. Start YuleLog, again answering the question as if this were a first time installation. Fill out the name and address form and then at the Licensed to screen, click on the Utilities button. Click on the Restore From Back Up Data Files button. This will read your data into the new copy of YuleLog and then you should be good to go.
Windows (Vista)
First start YuleLog on the old computer Click on the Save Backup Data Files buttons. This will create three files named Backup1, Backup2, and Backup3. These files will be saved in the YuleLog2 folder which should be in the Program Files folder on your C drive for Windows 95 - XP (or My Documents folder on a Vista machine). Copy these files to a floppy or to a USB Flash drive. On your new computer, install YuleLog, using your newest CD, as if it were a first time installation. When ever it asks, tell the installer that this is new installation. YuleLog needs to be installed in the My Documents folder on Vista Machines. When you get to the screen that asks where you want to install, click on the Browse button. Select Users. Then Select your directory (could be your name) It is whatever name you use to sign in to your computer. Select Documents. Click continue and this should install YuleLog in your My Documents folder. Then copy the backup files from the floppy or USB Flash drive to the YuleLog2 folder which again should be in the My Documents folder. Start YuleLog, again answering the question as if this were a first time installation. Fill out the name and address form and then at the Licensed to screen, click on the Utilities button. Click on the Restore From Back Up Data Files button. This will read your data into the new copy of YuleLog and then you should be good to go.
