oclHashcat fails

[Rox]

I am trying to decode a hash but oclHashcat fails:

# ./oclHashcat-plus64.bin -m 0 /root/Desktop/hash.txt -a 3 hash
oclHashcat-plus v0.07 by atom starting...

Hashes: 1
Unique digests: 1
Bitmaps: 8 bits, 256 entries, 0x000000ff mask, 1024 bytes
GPU-Loops: 128
GPU-Accel: 40
Password lengths range: 1 - 15
Platform: AMD compatible platform found
ERROR: ERROR: clGetDeviceIDs() -1


Do I miss something?
