Sons Craig Tablet model # CMP741e locked-cant to any kind of reset-HELP!

My son bought a Craig #CMP741e and was never prompted to link to google, it locked down and we cant figure out how to do a hard reset. We tried just about everything so he wouldnt lose his content, but at this point we would be happy just to reset it any way possible!

Any Ideas? We tried holding the volume & power buttons but it just brings up a locked screen stating you must sign into google to reset it???

I just bought it for him about a month ago and really do not want to buy him another!!
