EA APP

I have tried everything to get this darn app to work, I have tried uninstalling, and reinstalling, and deleting cache.... Nothing is making it work. I created a new account on my pc and for some reason it actually worked, but I don't want to have to switch back and forth between the accounts. Why can I not get on there? Hope someone has a issue fix, or someone to fix it at EA. if not they have lost a customer. Stupid that is that way.
