@Gin82 , have you uninstalled and reinstalled the app? Are you able to log-in to your account via the website and have you cleared the cache?
If none of this works, I would suggest ringing customer service so that they can reset your account.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
