CS2D 
Can't get CS2D running in Blitz3D

I have installed Blitz3D and got the source code from Developers page as well as the game files, CS2D 0.1.0.4 Beta, because I couldn't find the 0.1.0.0 files of it. As I've heard the later one is much slightly similar to 0.1.0.0 as the directory structure is still the same.
I did all the steps including the userlib part however I ran into a problem. Just prior to launching, the game crashes and prints "Memory access violation". I enabled the Debug mode and seems the culprit is
rgb=ReadPixelFast(x,y)from functions.bb file. The whole piece of code is this:

DC answers this. I apologise if the problem seems too easy to fix, I am new to Blitz and stuff.
