Hi, thanks for using JustAnswer.com I am Cris.
Connect your iPad to your PC with iTunes. You will then see the iPad appear click on it and click on Restore. That will wipe the iPad and walk you through the setup process again. See if that works and changes and leave the language to English.
Let me know the outcome. If you need assistance I can offer you Secure Remote Support and perform the restore for you. If the solution works please take the time to rate my service at the top and submit.
