Suddenly lost CPU as device

Hello,

Problem description: A month ago I had my CPU as a OpenCL device, I haven't updated anything since then, now my oclDeviceQuery doesn't see my CPU as a valid device, when I enter ..._CPU as a parameter to clCreateContextFromType it doesn't recognise my CPU as a valid device.

Here is my oclDeviceQuery.exe output.
