Hello Marco, and welcome to the forum.
Do not confuse Processor Expert (PE) with the company name P&E Microcomputer Systems.
CW version 5.1 is very old, and the MC9S08QD device probably did not exist at the time of release. You should forget about version 5.1, and use version 10.2 instead. This is capable of programming your demo board.
You will find that, as new devices are released, an upgrade patch is available for CW. However, I am not suggesting that you upgrade v 5.1 - it is now too old.
Regards,
Mac
