NVPP nppiResize return error? NVPP

HI:

I have download the nvpp 1.0, and tried to use it. I have trie the resize, but it returns NPP_ERROR:

/use openCV as IO/

    IplImage *src, *dst;
char *filename = "lena.jpg";
    src = cvLoadImage(filename,0); /*load  as GRAY , not color*/ 
    double scale = 1.3;

dstSize.width = (int)(src->width* scale);
dstSize.height = (int)(src->height * scale);

    dst = cvCreateImage(dstSize, src->depth, src->nChannels);

    /*set up region of insteresting and size */

    NppiSize srcNVSize, dstNVSize;
NppiRect srcRoi, dstRoi;

srcNVSize.width = src->width;
srcNVSize.height = src->height;

dstNVSize.width = dst->width;
dstNVSize.height = dst->height;

srcRoi.x = 0;
srcRoi.y = 0;
srcRoi.width = src->width;
srcRoi.height = src->height;


dstRoi.x = 0;
dstRoi.y = 0;
dstRoi.width = dst->width;
dstRoi.height = dst->height;

NppStatus status;

   status = nppiResize_8u_C1R  	( (Npp8u*)(src->imageData), srcNVSize, (src->width), srcRoi, (Npp8u*)(dst->imageData),
	(dst->width) , dstNVSize, scale , scale, 1);

  Then the status is always returned "NPP_ERROR", I do not know what parameter I set wrong.

  Is any one could help me? thank you.
