Black map after [[CCDirector sharedDirector] end]

Hi,

I am using cocos2d.
I need restart my app using button.
And my configuration start second time as views, controllers.

When I use [[CCDirector sharedDirector] end], before restart all, i have got warning : OpenGL error 0x0506 in -[CCSprite draw] 532, until I go to view with any scene.

Second problem is not-well render mkmapview (map is black only with roads).
