Ok. There are two ways to get an IDE-fix key:
1. you can still buy it.
http://www.vesalia.de sell it for 25 € plus shipping.
2. you can try to mail the original author for a free key
olliATNOSPAMelaborate-bytes.com
and don't tell me you can't afford that... Oliver Kastl is a great Amiga programmer and deserves the support.
