'App not installed' But it is !

[theVEnerable]

Hi
I use a HP Touchpad with ICS

Sometimes many apps won't open, I get the 'App not installed' message.

Perhaps it happens after I move them to SD card and it creates some problem.

Can anyone help me fix this Very annoying issue.

Thanks

I had this with a SanDisk 64Gb Ultra memory card after I moved apps to the SD card. I contacted SanDisk and they replaced the memory card because it is a known problem. The card becomes readable but no longer writable. Try reading and writing to it with your computer to confirm it. I had it happen with the replacement Ultra card they sent me several months later. They have since replaced it with a newer style card (not called Ultra) and the problem seems fixed. I hope this helps. It is a very common memory card failure. Let me know how you make out.
