Confused? Help?

[Soviet-]

Am I the only noob thats confused with how to install mods on this game through Steam? The mods for this game are the most confusing things I've ever seen! I need help with the following

- Installing the Fm_NewInteriors Mod
- Installing the GWX Gold Mod

Ok first off.

For the interiors mod I did the following!
I downloaded and installed the JSGME thing and using the individual download option, I installed it in my the following...

SteamApps/Common/Silent Hunter 3/

then created the MODS folder with the application

SteamApps/Common/Silent Hunter 3/MODS

I put the interior stuff in the MODS folder then enabled it with the program, I then started SH3 with Steam, the mod didn't work, I could walk around the submarine, I couldn't go to the engine room, I could do anything the mod said I could do, I tried doing the same again, still it didn't work.

So then I disabled them all, now I'm installing that GWX Gold to see if that will work.

TL;DR - Most confusing modfication installations in ze world

EDIT;-

Installed GWX Gold and now I have the list of all the mods in the Generic Mod Enabler - Im going to try interiors again. Also GWX works but it seems really zoomed in, everywhere I go it looks like im looking through a magnifying glass.

I'm uninstalling GWX as I dont feel im ready for it, at the moment I prefer the normal game, but I still need help with interiors!
