Database corrupt withouth any drives

I have an issue with my prime 4, as soon as I turn the unit on it gives me a message that says DATABASE OF (UNKNOWN) IS CORRUPT AND MAY NOT WORK PROPERLY, and I do not have internal hard drive or any USB device on the unit, is there a way to fix it since I called tech support stayed there for 38 minutes and only got a recorder, does anyone know how to solve this issue, since is my worktool, thanks

No SD-cards also?

No SD card as soon as you turn it on, the message comes on the screen

Have you tried connecting a correctly formatted USB device that has some music files and a database, and then turning the unit on?

i Will try it vut as it turns on says in the screen
