My selection tool isn't working. If I click on the 'white arrow' and try to highlight a layer object showing casing the blue, the object doesn't select.
My free hand brush tool doesn't work. If I click it, and try to draw with it, nothing appears on the layer even if the color is black.
My line tool also doesn't seem to be working. The same steps above, and nothing comes onto the page.
Any ideas why this is?

I even posted this same help on Reddit. I think I may have to uninstall and reinstall and that will be such a drag.

EDIT: I have got my free hand brush tool and line tool to work, but I still am having troubles with my select tool.

The white select tool is only for vector objects, actually. You sure you have a vector layer with vector objects?
