I was able to get the original version via 14 Day Trial, I'm able to log in my main account, but I've lost all of my old expansion disks. Is there anyway to download them somewhere?

Edit: Someone mentioned to me that the trial version includes all the expansions when you download, you'll just need to later buy a code and register them. Can anyone confirm this? I wouldn't bother since I'll find out later, but I'd like to know before this 5 hour download is finished if I could just go buy them in the mean time if necessary.
