What exactly do you have? A Kpro? What vehicle & ECU is it in?

Yes. The latest software version will work with any KPro.

Click on New calibration, choose the one you want to use, open that file, then click on the upload arrow at the top of the screen with the key in the on position to upload to the ECU.

i feel like he might have wanted to download his old software off the ecu first... oh well.
