Apple on Thursday responded to problems that came to light yesterday where corrupt files were downloaded from the App Store.

“We had a temporary issue that began yesterday with a server that generated DRM code for some apps being downloaded, it affected a small number of users,” an Apple representative told The Loop. “The issue has been rectified and we don’t expect it to occur again. Users who experienced an issue launching an app caused by this server bug can delete the affected app and re-download it.”
