BM Technic got shut down by BMW (indirectly). So you cannot reactivate now unfortunately.

Your options:
- Transfer your hard drive to another identical laptop.
- Purchase from cable-shack.co.uk or bmcables.com

The BMTechnic cable is still good for use with any software downloads for use with BMW (Rheingold, DIS, INPA, NCS Expert (Standard Tools), etc.
