I cannot register SOASE on impulse no matter what I do. I just recently bought the Entrenchment expansion pack, and I was able to install it, after many tries. But my computer had a major crash and I had to format the HD, and now when I try to register, it gives me the 204 error code saying that my key is incorrect or the email adress is wrong. I have tried that download that is avliable on the support site, but it does not work for me, or im just not installing it right. (which would be really weird...)
