As per title

I get an error you are not eligible for this offer...blah blah when trying to redeem a free game for pre-ordering.

I have played the beta in Feb so I'm pretty sure that this and the fact that my bank account is missing a substantial amount of cash should be enough proof I've pre ordered.

I cant see any emails asking to activate the game. And there is nothing in the uplay store I can see

Any help as to whats going on?
