So far, I disabled the view shaders, so I removed any reference in the script to .fx files. After doing that, the script was able to compile. I am guessing that I was using some old shaders that were no longer compatible, but I really don't know which ones. By the way, these are view shaders from the Wiki, so many of them were fairly old.

I am starting to re-introduce the built in shaders to replace the old ones.

Also, I was using a script called PP_Helper.c which I can't quite remember where I got. Maybe from AUM? It looks like A8 has a built in command pp_set and pp_add that has the same functionality, so I will be using those...
