I had no choice but to register Bryce 5 when I bought it, because when i came home and installed it, the serial number they gave didn't work, I had to call them and use up 45 minutes of long ditance to get a working serial number... I love Bryce, but I hate Corel with a huge passion. Unless Corel releases a Bryce 6, I will never even consider Corel for any software purchases...They just make a bunch of crap anyway. The only good software they offer is stuff they aquired from buying it from someone else...Sorry, I just have a deep problem with Corel..... Thanks for the tip..
