Error message

[darkoff]

I have been able to successfully mine in the Deep Bit and BTC Guild mining pools for about 1 week.  But yesterday I put a new graphics card in my computer, and now when I try to mine, I get the following error message: "Traceback (most recent call last): File "poclbm.py", line 27, in ,module. pyopencl.LogicError: c1GetPlatformIDs failed: invalid/unknown error code".  Does anyone know what this error message means, and what I can do to fix the problem?

Are you on windows? On Windows you need a dummy plug in your second video card or the driver will not activate the card.
