My Loaded Map is All Black

Saved my map a few hours ago and when I loaded it back up it all turned black. The Dev Kit is alright and working, and my map is still there its just my map is all black and won’t let me paint over it. Any help on how to fix it would be greatly appreciated.

Have you assigned layer info objects to each material?
Are you following a tutorial?
What landscape material do you have assigned to your landscape? Double check that it is still assigned.
Make sure you have the right landscape selected that you are trying to paint. There is a drop down box in the paint window to select landscapes (if you have more then one.)

Could you provide a screenshot with the paint tab open, please.
