Unable to add M&B to my account (Invalid serial code)

[Xtrah]

I bought Mount & Blade on Steam a couple of days ago. I'm unable to add it to my games at this site, but I managed to add both Warband and WFaS.

It just tells me that it's an invalid serial code ("Invalid serial code") when I press "Add game to profile". I was looking around on the forums, didn't find anything.

Is it 5x5 or 4x4 serial key? You should consider looking around for the changing from 4x4 to 5x5[or the other way]

E: I think I've got it

Link to change 5x5 to 4x4

It's a 4x4 key.

It is possible that the most recent set of keys sold by Steam have not been entered into the Taleworlds.com system. Will flag this for the Developer typically responsible for keys and such to be aware at least.

Thank you.

I am also having this trouble, I bought M&B on steam with a 4x4 code yet cannot register it on the site.

I bought Mount & Blade: Complete 6 months ago from steam. I am also unable to add M&B to my Taleworlds account. I was able to add both Warband and Fire and Sword.

Bump - any more having this problem? Have the devs left us?
