wp8 .plist file loading error

Hi, I am trying to port my game to wp8. I have used zwoptex flash version to create .plist files. but it doesn’t load. I found this in the forum http://www.cocos2d-x.org/boards/6/topics/1072. it is iphone tough. its very similar problem.

cacher->addSpriteFramesWithFile(“blablabla.plist”); error is right here.

I don’t know where is the problem but I hope you guys will help me.
Thanks.
