My computer has an asus-p6t6-ws-revolution motherboard with a Corei7 965 processor and 3 x gtx 280 graphic cards. I am running 10.6.6 and have had QE/CI until today.
I am very grateful for your help earlier. QE/CI has worked flawlessly for me.
When I switched on my computer no QE/CI was present (Menubar is not transluctant. No application requiring QE/CI works. Also, the cards do no longer show up in system profiler. It is as if my efi-string is no longer read correctly by the system. I have changed nothing since we got it working.
GeForce.kext, NVDANV50HAL.kext and NVDaresman.kext are loaded. Still no QE/CI.
Are you booting from a USB drive or directly from your hard drive. Go through your extra folder and double check the right things are there and that the wrong things aren't (kexts and com.apple.boot.plist). Also see if you have an extra folder on your Hard Drive(you should only have one. Depending on what version of OSX you are using re-install the latest update.
Thank you very much! I solved the problem thanks to your reply.
I had by mistake installed another version of chameleon on my OS X partition. I have one small partition for my bootloader and one for OS X and chameleon were installed on both. I removed the extra folder on my OS X partition and everything worked again.
