Can't get A*Pathfinding to run, "Identifier expected" error

Hello,

I downloaded the free Version for testing purposes and followed the first Tutorial. I can’t execute the Script under “Moving Stuff Around” because Unity gives me an “Identifier expected” error.

Here’s a Screenshot: http://s1.directupload.net/images/140606/ejzyoktq.jpg

As you can see, the problem lies in line 5 of the code
using %Pathfinding;

Unity does not seem to recognize the identifier. Anyone can help me solve this issue?

I imported the downloaded package into Unity, created a map with a terrain ground layer, obstacles with obstacle layers.
Then I created an empty and put the Pathfinding -> Pathfinder component on it, configured the Grid Graph according to the Tutorial page.
I created a capsule, put the Seeker Script onto it and after this I copy & pasted the Script from the Tutorial into a new C# Script and the mentioned error pops up in Unity.

Regards
Angelo
