Ok, I'm not addicted like my wife is to this game, so I'm posting for her. She is running stock Android Froyo on her Moto Droid (original), and can't get Angry Birds Rio to play. It seems to start, and then dumps right back to the home screen. I checked the .android_secure/ folder to look for the smdl2tmp1.asec file, but it isn't there. I've tried installing and reinstalling.... Any thoughts or help would be appreciated.
