I have seem to run into a little snag, I have purchased LOTR BFME2 ROTWK, but the problem is that i once owned LOTR BFME2, so i have the files on my computer, but i sold the game and since them i no longer have the computer that it was originally on. But i did copy the files onto my desktop computer so that i could play them, and that was fine until i bought the expansion ROTWK and tried to install it, it says i must have BFME2 on my computer in order to install the expansion.Though i do have BFME2 on my computer, it is not 'technically' installed. How can i get around this without buying or downloading BFME2 again. any help would be appreciated! Thank you.
