When using adjustment brushes, my screen will suddenly turn blue and the following message appears: unexpected_kernel_mode_trap. I've searched for an answer and have tried a clean boot, uninstalling and reinstalling Lightroom, unchecked "use graphics processor" under preferences. It's a tiny bit better, meaning I can edit a bit before it crashes, but it still happens. I have a wedding to edit and I'm running out of time!! I'm going to have to switch to Photoshop for my precise adjustments, but it's not the same.
