Can I use the Eu EotN on my Us GW Trilogy Version?

Hey there all =)

I just bought an EotN Expansion, when I got home I realised that it was the Eu version.

I have the Guild Wars Trilogy edition, My Question is, can I use the Eu EotN on it as in its all the same?
Or do I have to return it to the store and get the Us version?

Thanks in advance for your help =)

Its all the same. Just add your access key to your account and you're good to go.

I'm pretty sure it will works, you just buy an activation code for your game.

SWEET!! >_<

Thanks alot guys =)
