Help paint will not work!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

When i decide the paint my terrain i click on it and it will not show up!!! i was not far but near, so why does this happen??? I reinstalled it 3 times! and still did not work

Restart Unity and try again. Restart your computer, if necessary.

If it still happens -- Upgrade to the latest drivers for your graphics card.

You need to explain it further..

Do you see a blue shade circle on the terrain? If so, than alter the settings. If not, than maybe try Unity 2.6 and wait until another update comes out.

But I also agree with ina, it probably is your graphics card.
