Its not actually a problem within rendermonkey its just when I use it in my own prog.
Heres a copy of my code if it can help anyone solve this problem:

Later on in the day having turned off my computer I came back to programming my terrain and found that it no longer worked!
Closeup
I then found that if I run the original shader in rendermonkey (the version before making alteration to it to get it working in directX prog) and then run my terrain engine it works fine again. If I restart my computer it also continues to work until I shutdown my computer completely.
This problem didnt occur when I just had the per pixel lighting with no bump mapping so I`m guessing its something related to that.
This seems real strange to me. Anyone have any ideas why this is happening? thanks.
