Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I presume you are entering the Apple ID, and password, on your iPad itself.
When did the ID and password ***** work, previously to this, on it?
How long ago was that, please? that you set up your current iPad password?
Then you will need to reset your Apple ID, I think.
Do you know how to do that? or do you need instructions?
OK. I am preparing instructions... meanwhile, thank you for your patience.
Pardon me - a few other cases demanded my attention for a bit.
and enter your Apple ID's registered email address to begin.
(I hope you recall what that email address was - given that it was 3-4 years ago. Also, be prepared to check for an email sent to that address... by some other means than through your iPad, since it is out of commission until the reset process is done.)
Let me know if there are any problems, or if any further advice is needed... and let me know how it turns out, especially if all goes well, please. Thanks.
