Any other errors on screen? Most of the time this means the OpenCL failed to start
* no GPU found (probably not your case)
* worksize too big (not your case if you are not on Amazon)
* no memory left on GPU
In your case, it looks like
OCL error: CL_MEM_OBJECT_ALLOCATION_FAILURE (clEnqueueNDRangeKernel failed.)
edit: you sure you have up-to-date client/generators? I see you were last active 24 days ago, minimum client version is now 1.140, hopefully you have also a kardashev-generator too.
