Crash report

Hi… When i run the UE4 look this crash report… How i can fix this problem?

Hi Ramig -

This crash is caused by altering the World Grid Material in the Engine Content directly instead of copying and making changes to it. You can correct this crash by going to C:\Program Files\Epic Games\4.9\Engine\Content\EngineMaterials (Default Installation Location) and Delete the WorldGridMaterial.uasset.

Then you will need to open the Launcher and Verify the Engien version again in your Library.

After doing this the crash will not longer occur.

Thank You
