I am receiving an error whilst I am trying to do a backup.
This error means that you have not chosen a file location for your backup - choose a different location when backing up.
Go to File > Backup Data Files
Choose a location for your backup. Click on the yellow folder to browse your computer for the desired location.
This can be anywhere on your computer, a disc or on an external hard drive.
Click the Backup button.
The backup will now complete successfully. If not please contact the support team at Practical Systems.
