Okie Dokie im in a bit of a pickle here

Hey guys new and everything so hey! Anywho! i had a friend who had prophecies and he gave me his email address so i can play it, then i have bought nightfall and factions but they are on my email address anyway i can get them on the same so i can move my players about?

Nope, you can't combine used keys. You'll need to buy a new prophecies account to add to your factions and NF.

Also it's technically against ANet's EULA to play on someone else's account, so be careful.

Better just suck it up and restart your chars on your own Proph account, which you should add to your own Factions/NF email address. (Then ask your friend to play on his account long enough to hand you all the stuff and money on his account lol.)

Yup, too late now but you should have got him to change the email adress on his account to yours, then applied the NF and Factions keys to that.
