When I try and install something I get "could not be downloaded due to an error (-101)". Similarly when I try and update anything. Its behaviour is very odd too, after I've been told that I can't install/update something it perpetually has it as "downloading" on the installed apps page, and the "Stop 1" button does nothing. Going to Google Play in a browser and installing from there it says "This will be sent to your phone" and does nothing. Force closing and wiping app data does nothing, and I've done both several times.
