Hi qsc, welcome to the forum. Nice to have you as a member of Android Tablets. You're probably going to have to do a factory reset, which will restore it to the way it was when it left the factory. How that's done depends on the tablet and I'm not familiar with yours, so I'm moving your thread to the Android Tablet Q&A section for you. Hopefully, someone familiar with your tablet will reply there and try to help you. Good luck!
