Capt Sims 727-100 help

Looking for some help here.

I just purchased Capt. Sims 727-100 pro pack, and the 727-200 freighter expansion pack (download version) the other day. I have gone to there website, http://www.captainsim.com/ to look for the manuals. I did download them, but im having problems with them. After i extract the files, i get a code (like a programming code) of some type for all 3 manuals downloads. I also registered to there forums, received my activation e-mail. tried to activate, but i get a error message. After i try to activate my account. I had also googled it. But i can't fine there manuals anywhere. If someone can help me out, with a different link or if you can e-mail a copy of the manuals, i would really appreciate it.
I really like the 727's. I know they are a older type of aircraft.

Thanks,
