adding a unit and using none of the existing text in the game

[jethro]

was wondering if anybody knew how to make a unti(or any addition)to cpt2 without using any of the exsisiting text,ie adding all the text in the library and the other files.ive managed to make some units and im trying to insert them without changing any of the exisiting units,or using any of the descriptions.seems i cant get the descriptions in the library to work properly.keep getting a crash.occasionaly it shuts the game off.
