I just uploaded my files to Lightroom and when I switch to the develop module all I see it blue where the picture supposed to be. How can I fix this?
This is a GPU related issue. Please update your GPU drivers from the manufacturers website.
In the mean while, disabling "Use Graphics Processor" (Preferences > Performance), should help load the Develop module.
