I have/had the 2 Angry Birds game on my X. Tried updating the Season version and it just won't update. Tried anything I could think of including pulling the battery. Finally thought I'd just delete both of them and redownload. Now neither one will download nor can I restore either one from backup. All other programs work and update as they should. When trying to update the Season version I kept getting an error 18 which didn't mean much. Even from backup it asks if I want to install them and then after answering yes, it goes through the motions but says it didn't install. Gives no reason. Any ideas?
