Anyone else struggling with v5? I downloaded and it launched, but that is it. When I move sliders the histogram changes but the image does not. I uninstalled with App Cleaner, doing a secure delete (writes 0 over the removed data) and am downloading another copy hoping that the first file was bad.
Edit: FWIW I also have the LR3 beta installed. Any chance it did something to my raws so C1 couldn't open them?
