Can't Log In On PC App

When I log into my developer account on my browser, it works just fine. But when I try and log in using the actual app so I can connect my headset to my PC, it says the email/password is incorrect. I've made sure that the credentials that I use for both are EXACTLY the same, but it won't let me log in. I contacted support thinking that it might be a server-side issue. I thought that maybe something wasn't going through to the App. But they just redirected me to developer support which doesn't have a way of contacting them about it as far as I can tell. Does anyone have any idea as to what I can do to fix this?
