Won't install

I heard about this mod and it looks great. Reinstalled my copy of rome and the 1.5 patch, then downloaded 1.0. The download went fine, but when I hit install, it will check the "integrety" and then say the archive is corrupted and finally shut down.

Plz help me

If your download is corrupt, you'll have to delete it and redownload it. It didn't quite finish downloading or something similar.
