I got error 203 from ordering too many accounts? O_O - Is there any other trusted store online to buy the game??

[Cooolr]

After creating and upgrading 3 accounts I create my 4th trial account and try to upgrade it but get error 203. Which is probably some cache / cookie / or ip problem.

What I find weird is that they dont' let me purchase. Yeah that's what I don't get to do. But I managed to create loads of trial accounts though.

So does anyone know a fix to this error?

I just got the idea of purchasing online but from someone else. (I'm too lazy to go to a store ATM)
And I've heard of shatteredcrystal (com) for being some trusted site but they are all out of the EU original game, non expansion.

So I'm trying to find a trusted seller online so I can purchase from them and then just add the authentication key on my account.

edit: or I could use a own proxy. But I wouldn't use any proxy. Probably a proxy hosted on my own servers.
