Are you running Windows 7? If yes, so Win7 is just not supported, Win8.1 and later are.

[Quake4]

yes. win7. why win7 isnt supported?

[jceminer]

Because my OpenCL code is not compiled like with xmrstak, but somehow injected into the drivers, to prevent hacking involving stubbing the OpenCL api (a simple hack everybody can do). It also allows a very fast init, less that a second per thread, with no need to cache the code like stak or xmrig do. But that technique doesn't work on Win7, and i could not find a way to keep both security and compatibility so I dropped Win7 support for GPU (CPU mining is ok down to Vista32). Go to the Bitcointalk topic for the full story.
