Hm, what browser are you using? Are you still unable to login? If you're still having issues, try logging in with incognito/private browsing mode and see what happens.

It doesn't work in Firefox or in IE (I don't have Chrome downloaded). Oddly enough, the download button, which is greyed out in Firefox, is green in IE... but it still says I'm not logged in on both.

I click the "Log In" button and accept logging in through steam... and it returns me to the moddingofisaac homepage, but I am not logged in!
I have tried several times, and can still not download anything.
