I keep getting a "Unfortunately, Google Play services has stopped" message when an app downloads or updates. Possibly related, or coincidental, I can't get any of my Google Play books to display. Carbon mentioned in a G+ community that they thought it may be related to a similar issue reported earlier about corrupted app file versions getting saved to the SD card. I couldn't find this thread. Wondering if anyone here may have come across this issue, and a possible fix.
