My 13.3" Hanspree was working fine, then it told me the System had an Update to install. I clicked to install Update and it appeared to go well, did its thing and rebooted to Home Screen. Then I wanted to install Google Play....I had previously installed it OK. Now the tablet will let me get as far as the "INSTALL" for Android market but sticks at "Download completed 0/4" On looking I find that all my previous Applications are downloaded but are not able to be opened. Can anyone help please? The tablet was new in January 2014.
