It could be any number of things. Have you optimized your pc for audio production? Have you disabled wi-fi? Are you plugged into a USB2 or USB3 port? Did you install the drivers from the included disc? Or did you download and use the latest drivers from this site? Have you performed a proper uninstall/re-install of the drivers? You said it's not working in Ableton. Did you try it with Studio One or any other DAWS?

That being said we can help you better now and in the future with a bit more info......if you will post your system specs in your signature, (see my sig), we will be better able to troubleshoot your problems. Without knowing what type of pc you're running, we often can't recommend a "simple fix".

If you have not already done so please READ THE MANUAL!

I fixed mine. I Literally changed USB cable.

I tried uninstalling/reinstalling drivers and software. I tried USB 2.0 and 3.0 ports. Nothing was working until I switched usb cables. I have a new cable and also a cable that came with the audiobox that both don't work. They work for other usb devices, but I only got the audiobox to work on another usb cable that I had from a few years ago. Idk, but it works.
