Error running oclhashcat

Hello,

I'm trying to run hashcat. I installed the latest AMD drivers (14.4) as mentioned in the wiki but every time I run hashcat I get the following error:

oclHashcat64.exe -b
oclHashcat v1.20 starting in benchmark-mode...

WARN: ADL_Overdrive5_FanSpeedInfo_Get(): -5

Device #1: Tahiti, 3072MB, 1000Mhz, 32MCU
Device #2: Tahiti, 3072MB, 1000Mhz, 32MCU

ERROR: clCreateProgramWithBinary() -42


My environment is:
- OS: Windows 7 x64
- GPU: Radeon 7990 6GB
- Driver: Catalyst 14.4 (14-4-win7-win8-win8.1-64-dd-ccc-whql)

Thanks!
