We've changed the calculation of Hardware Ids starting from MZpack 3.14.0 beta version for more robust checking of your license.

The upgrading sequence is:

1. Install MZpack 3.14.0 beta or newer version

2. Contact support with a request for activation reset

3. Wait for the reply. DON’T run any previous version of MZpack on your machine now!

4. Once you will receive support reply you may run MZpack 3 products.
