Hey Paddy,
What Version of Windows and Band-in-a-Box are you currently running?
First, always make sure you are using the latest update for your version:

- Right-Click on the Band-in-a-Box Icon or bbw.exe in your bb folder.
- Go to Properties > Select the Compatibility tab
- On the lower half of the menu, ensure 'Always run this program as Administrator' is checked
- Hit Apply > Ok
- This will give Band-in-a-Box administrative privileges, and will avoid most Access Violation errors.
Please Note: When running Band-in-a-Box as an administrator, Windows will ask you if you want to let the program make changes to your computer each time you run the program. Just hit 'Ok' each time.
Please let us know if the problem persists.
