Hi there! I edited out your email address... since this is a public forum, anybody can look at these pages - not just members. We sort of frown on posting personal contact information like that: we don't want anyone to get your email address and do something less than noble with it
As far as your tablet goes... it's a brand I've never heard of. Sounds like a cheap Chinese knock-off Android tablet, which I encourage people to avoid like the plague. But you have it now, so let's deal with it. There should be a small pinhole on the back. That's the RESET button. You'll need a straightened out paper clip, or maybe even a SIM extractor tool, to get in there. Hold that button in for about 30 seconds. That should factory reset the tablet to default, out of the box condition. Your apps, data and settings will be wiped, but at least you'll have a tablet again.
Let us know if that helps. If it doesn't, then your operating system is likely corrupted. The only fixes are (a) reflash the stock firmware... and I'll bet a paycheck that doesn't exist; and (b) return the tablet to the manufacturer and let them reflash the stock firmware... if you can find them.
