Save data error and game crashes

NEW SAVE DATA ERROR

 

I have 2 vitas a 1000 and 2000. I've been grinding trophies on the 2000 no problem but I have recently downloaded some games into the 1000 and it has given me nothing but trouble and a terrible experience. First installing the games kept messing up. Got them installed and running. Now I'm playing UNIT 13 beat the first mission and then it said 

*NEW SAVE DATA ERROR*

 

When I first boot the Vita up and launch UNIT 13 error code pops up.

Go back into UNIT 13 and Vita restarts. Vita boots back up and game launches fine. Have tried deleting and reinstalling and same thing happens.

Has anyone ever experienced anything similar? If so is there a fix?
