oclhashcat+ error in win7x64 ATI
I am using oclhashcat+ 0.3 in a Windows 7 x64 machine with 11.7 catalyst drivers installed

When I try to use oclhashcat+ get the following error:

Platform: ATI compatible platform found
ERROR: clGetDeviceIDs() -1

I'm doing anything wrong or I forgot something?

Thanks in advance,
Which card do you use?
Ups, sorry, I forgot, It's an ATI 5750
I have tried older drivers (11.4) and now oclhashcat+ it's working fine. Hope this help others with the same problem.
