CAN SOMEONE HELP ME WITH THE SOFTWARE

-I CAN’T DRAW
-PROHIBITION CURSOR
-RED BOX LINE ON DRAWING & CAMERA TAB
-WATCHED ALL THE TUTORIALS NOTHING WORK
-TRIED ALL THE GIVEN HELP FROM OTHER USERS NOTHING WORK

same here

You need to add a layer first. You will not draw on table (your mom will stop you from doing that). The same way toon boom stops you from doing that. A layer is like a sheet of paper. When a layer is added, select it and then select pencil or brush. Then you can draw.

I have this problem
