Itunes won't recognize my apple id

Thanks Limnos! I wîll contact Apple support. The ipad is suddenly only bringing up my father's email that was used for the original login years ago and has been deleted completely. I have used this ipad with my id for six years, so no idea why this is suddenly appearing! Thanks again for your response!

Thanks again for your help! Yes that is exactly when issue started...while trying to update a game centre game.!! I just recalled that the same game was orinally downloaded with another id (which is now nonexistant) and that did pop up for password and I hit it by accident to sign in for uodate. Now it doesn't recognize my id anymore to play my game that has been in progress on ipad for six years with my id... or get into itunes or app updates as i mentioned. I am totally signed in everywhere ok so I may just have to ignore this game and updates and use an alternate ipad... thx for info re resetting and all your help! Have a good day!

One more thing.....Apple Support's conclusion was that I have to get a court order to access and delete my father's id that was originally used here six years ago. Think I will pass on all of that!! 🙈

Success!!! I got brave and deleted the game app....then reinstalled it and it did come back fully entact with my gameplay!!!!! Happy Day! Thx again :)
