Hi there Carolyn and welcome
You will need to get the windows 10 drivers for this.
First, uninstall the unit by clicking start, typing in device and printers and clicking on it when it appears.
Then right click the unit and select Remove.
Then go to control panel, uninstall a program and uninstall any programs you installed for the unit.
Once done, restart the computer
Then click on this link and download the driver package
Once done, run it and you should then be able to use the unit again
Let me know please how you go.
