I paid and pre-ordered Entrenchment a month or so ago and have been happily playing the beta with no problems. However, with this new patch I can't seem to play it any more. I reinstalled the original SoaSE like the forum post said, and then went to reinstall the expansion. It then popped up with a message saying that my registration wasn't valid. I found what I thought was my registration number on impulse and plugged into the update registration page along with my e-mail. It wouldn't take it and claimed it was invalid. I checked and re-checked multiple times to make sure that the code was correct. I don't know what to do.    Any help is appreciated!
