Recently, I've been unable to download or update my apps through any of my Apple devices: MacBook Pro, iPad, iPhone5, iPod. I am able to make purchases but I am unable to download the apps. Same issue for updates to existing apps. I've searched the web and other forums. Some forums have suggested downloading the app "Trash It" for error code 8003 issues. I've tried that but it still doesn't work. I also use a Cisco router. Would that be the source of the problem? I haven't had these issues before. Does anyone have any suggestions?
