Can't change my password due to my username

Hey so I can't change my password get the error message:

Username must begin with a letter and contain only alpha-numeric characters

I created this account like 20 years ago or so apparently the username requirements have changed. And I don't think I can change the username. Can some admin help me out?

@-prankfurter-: try emailing support support@gamespot.com

@-prankfurter- I can see if I can help. Do you want to change your name to just "prankfurter" if it is available?

Lemme know. Thanks!
