sylex3 problem

Ok, just started to fiddle around with sylex3, but got a problem with initializing it:
Code:

---

plugindir = ".";

include "movement.wdl";
include "camera.wdl";
include <sylex3_csr.wdl>;


var video_mode = 8;
var video_screen = 1;
var video_depth = 32;

var shadow_stencil = on;

function main()
{
	dll_open("Sylex3.dll");
	SLX3Initialize(SLX3_RUNMODE_DEBUG ,"TFOH sylex + movement test");
	level_load("level.wmb");
	camera_init();
	wait(1);	
}

---

this code gives me this error:
SLX3Initialize(SLX3_RUNMODE_DEBUG,@4)>
MAIN.WDL 21:0 (): Parameter unknown SLX3_RUNMODE_DEBUG

I've got a feeling it is a stupid mistake i'm making, but i really can't see it. Would you help this sylex noob out

*bump*
