When I star the tablet its write unfortunately kidoz is stopped please help me

It is possible that newest version oplay store is no longer compatible with older tablet. Try to turn off automatic updates for that app and see if it helps. More info here:

Nope. You'll need to reset the tablet. This will mean you also lose your information on it.

delete the software, reinstall the software
you mite have to go to rca manufactures web site, look for technical help, customer service, or FAQ may also help

Hi Roberta
Perhaps an Incompatibility.
Time to Rely on the Warranty... It does have a warranty... right
If Not....
There is a service agent or even the people you bought it from!
When buying electronic products it's times like these that you need good customer service.
I try to think of this just before buying my product.... even if it costs a bit more.
apple costs more but it's dependable
Good Luck
