I have installed the new lightroom CC and the miniatures are ok, but in revelation there's a blue box over the the image with a big cross over it. I've uninstalled it and re installed and no luck.
Someone can help me?

Go to Edit >Preferences > Performance, and uncheck Use Graphics Processor. That should fix it.
Now update you graphics drver, and try turning it back on.
