dino cris.2 need help

[patch god]

The patch will never mess the game up. the only thing it can do is not crack the game. it could be choppy because of a number of reasons

The cd burner is crap
The Blank cd is crap
You are burning at a high speed (or sometimes a very low speed)
your copying the game "on the fly"
You are using a program which is not fully compatible with your burner

Those are all the reasons i can think of from the top of my head

Good luck
