Unable to log in

Does anyone else have trouble logging in on D3 via Innerspace? I sent a message to them asking
if they could help but I haven't gotten a response yet. When trying to log in I always get the same message
on every account: "We couldn't log you in with what you just entered. Please try again."

I already know that my information is correct, I can log in on the battle.net app with every acc.
I've tried uninstall and reinstall the battle.net app, deleting the cache and so on.

Anyone out there who can help?

Have you disabled Key Maps, as suggested in the Quick Start Guide?

Thanks alot! Wow this is embarrassing... Don't know why it happened now when it never has before though :p
