VIP Bonus "codes" not working

Ello all, As title suggests ive been having issues redeeming the emailed VIP codes. When I click the “email code” button in this case “DONTFORGET”.

I am taken to a link Borderlands VIP- Codes, where I can click a Shiftcodes button, I do so an input the code, but nothing happens. The code length seems incomplete,

IE- DONTFORGET, compared to the standard golden key codes 4638-ghgs-346g-4564-gj23 etc etc.

Anyone know if im missing something?

try the vault code tab
