Beginner error. Please help

Hello,
when I was trying for the very first time oclExample.cmd on Win7 x64, I keep getting the following error:

GPU-Loops: 1024
GPU-Accel: 160
Password lenghts range: 4 - 55
Platform: AMD compatible platform found
Watchdog: Temperature limit set to 90c
Device #1: ATI RV710, 256MB, 0Mhz, 2MCU
ERROR: clBuildProgram() -5

Why do I get this error ?
