Please remember to use the right files. Predator files can be used on any Dragon/T-Rex, but if you have a T-Rex 4.6 you might want to use a updated Predasarus file.

Dragon CAM = Predator files Only. 
T-Rex 4.5 = Predator/Predasaur files (but no Security Update feature) 
T-Rex 4.6 = Predator/Predasaur files (with Security Update feature)
