Default LG L70 launcher problems

OK so I've had this LG L70 for a month now still no root. But that's not what I'm here to talk about. I'm here to ask for help or info with my problem. So the stock launcher is OK but no wear near better them sum or these aftermarket launchers... Next launcher in general. Well after downloading next Launcher I tried to set up my home screens with the same widgets I had on the stock launcher with no luck. It tells me there is a problem with the widgets tap to reload. When I tap they disappear. Anybody know how to fix this problem? Maybe some kinda work around. Thanks for any info.
