Welcome to iMore! Try going to
http://appleid.apple.com and logging in, just to make sure you have the correct Apple ID and password and there isn't any account-level reason you can't log into your iPad. If all looks well there and you still can't activate your iPad, boot into recovery and allow iTunes to download and install a fresh copy of iOS. Follow the link for more info on that.
