InitCL, error

Hi, everybody:

My grahpics card is ATI Radeon HD 4670?when I  ran the sample "Image Convolution Using OpenCL -A Step-by-Step Tutorial" downloaded in this web, an error occured when going to the InitCL function,error message is:

   err {err_=-32 errStr_=0x0047e648 "clCreateContextFromType" } cl::Error

. And for CL_DEVICE_TYPE_CPU and CL_DEVICE_TYPE_GPU, the same error.

What's the problem?
