Can't login due to 503 Server Error when clicking "account" button on main website

Hello, I am a student who is using RapidMiner for a Data Mining class. When opening the program it asks me to log in so I can install my license. Unfortunately it just tells me there's an unknown error. I tried going to my account to manually input my license but I cannot login at all (Error 503). I need access ASAP for an assignment, any help is greatly appreciated.
