PBE: (Tutorial2) Problem with spatialManager variable

I've just started with PBE. Now trying to follow few first tutorials. Have problem with the second one(http://pushbuttonengine.com/docs/Lesson-02.ht开发者_Go百科ml). E.g. this line of code: spatial.spatialManager = PBE.spatialManager;

throws the: Attempted access of inaccessible property spatialManager through a reference with static type Class.

Could you please help me. these are my first steps with PBE...a bit hard :(

Actually the problem was with incorrect version of lib I've used. After PBE update (to 1.0) it worked
