Multiminer suddenly stopped detecting my video card. All of my ASIC miners (ICA) show up just fine, but no OCL any more. I clicked on the "Detect Devices" option but it still isn't seeing my video card. I am able to mine with my card using GUIminer Scrypt, but I want it to be able to automatically switch to the most profitable currency.

My computer did freeze up and I had to reset it when I got home. Since then Multiminer hasn't been seeing my card.
