UI Problem HELP?

[DanieAndMe]

I Was Working On The UI For My Theme And When I Added The File
"UIPopupAlertSheetBackground.png"
It Comes Out Full Size No Problem
But When I Add @2x To The End To Make It HD It Comes Out Small To Where You Can Barley See Anything.Any Idea On A Fix Am I Doing Something Wrong?

Thanks Guys

Is the @2x.png file at twice the pixel dimensions (e.g., 200x80 px as opposed to 100x40 px) as the original "UIPopupAlertSheetBackground.png" file?

Also make sure your resolution isn't too low on the @2x file.
