Hey guys,
Reason why the link is no longer working is the unrealengine webpage has been updated as of November. My apologizes, the link provided in my previous response in June is no longer in service. You may send your submission over at Publisher Portal from now on.
As for your issues with “create account” can you explain in for details on where you are experiencing this issue, any technical error codes you see, or screenshots where you are stuck at? Anymore details you can provide, I can look into this further for ya.
Thank you,
Reuben
