I just allowed my machine to do an Adobe update and now when I open any project it displays the following message "This project was last used with Mercury Playback Engine GPU Acceleration, which is not available on this system. Mercury Playback Engine Software Only will be used." Until now I have been able to utilize the GPU acceleration beautifully. Is it just a bad update ? Or does someone know how to fix it?
You will need to redo the 'hack' to get your card working again. The update overwrites the text file.
