EHM The Blue Line

Please Help, I'm new to the EHM world and found this site which is fantastic!! I've downloaded many of the update files such as face packs etc for EHM 2005. I've also downloaded the game editors. The problem now is I don't know where to put the downloaded files. I've tried searching the boards but everything I see relates to EHM 2007, can somebody kindly point me towards the 2005 version please.

Thank you in advance.
