Hi...
I wonder if you now have your crash errors solved?
As I recall, I had similar crashes and I believe that the reason was because the game somehow was finding the improper effect code file/definition.
You will want to track down the proper file/definition and make sure that your project can find it during run time...
In other words.. Where is the water_par defined? And, can the game find the definition or file where it is located?
Also, you might try scripting out the effect line and run to verify if that truly is the problem...
Hope that helps...
