Yes, you need to have a proper name (Not something like zzzzzz) as your handle ( Character creation rules ), but if that was the problem you would have had a different email back...

What's the problem with using a proper name? It doesn't have to be your actual name, you can just make one up, it just has to be somewhat more serious than in other games.
Reply to the email you got, as it says reply if you do not know why your application has been rejected, then explain your circumstances to syn and hopefully it will all sort out...
