Hi @Anonymous,
Welcome to the community! 
The first thing which you can try is to fill out THIS FORM
The next thing which you could do is to go through THIS THREAD as reference as this is a problem from time to time.
In the last post of the above-mentioned thread, there is a username and password which you can use in the meantime and test to see if it resolves your issue until Autodesk comes into contact with you.
I hope this helps!
