Gate model is horizontal and i want to to be vertical

[Sheep_p]

I downloadet a gate model:
Tor - The Hive Workshop - A Warcraft III Modding Site
As you can see on be attached picture, the model is horizontal and the gate which i based it upon is vertical. I need the gate to be vertical and i dont know how to fix this myself.
So if anyone please could tell me how to turn the model, or in other ways, fix the problem.

thanks form sheep.
