They were uninstalled. GUIMiner shows 2 options for mining; CPU and Cayman. I select Cayman which I assume is correct for the 6950 gpu.
Same issue with me. Been at it for hours and hours.
Here's what I found: I found a Bitcoin directory in two locations. One in the roaming profile and one in C:\Program Files (x86)\Bitcoin.
When I put my bitcoin.config file in the (x86) directory and started the gui, voila!!!! It worked. I then started another gui for my second device and they both crashed

Closed them both out. Opened one gui and am currently running only one device. Need to figure out how to modify config file to get both running. Feedback?
