It looks like Google has temporarily pulled the .apk encryption feature. Users were reporting problems of legitimate play store purchased apps from being able to run possibly due to a bug in Jelly Bean that didn't handle the decryption properly. Users who now re-download apps will download an unencrypted version of the app until Google can resolve the issue, probably with an OS update.
