There is a fishing game on face book I was playing a few weeks ago but when I reached level 10 my computer froze and I could not get back on it. We had to call a Windows tech to help get back on.

So I go back to the game and I tells me it ill not load because a dll file is missing. The program that it wants me to down load is called Unity I guess that it is needed for the games because it is a 3d game. Doe anyone know if this program is safe or not?
