Cannot Launch / System Error

[Entelex]

I used the 30 membership when installing the game and creating my account which was the only one required to play the game.
I've been playing the game 1 day after launch and this problem has only just arose.

I just used the 'Product Registration Card' now, the reason I didn't when I got the game was because of errors and I just forgot about it.

I did manage to get onto the game before you replied, got 90k, then a lobby error then back to Launch error / System error
