How do i install SBMP? Ive tried several methods!

Ok, i waited 2 hours for the Spacebuild model pack 2(Damn neighborhood shared line), then when i go to install it, and boot up gmod, it hasnt worked!
T_T
It looks like this
SBMPA2>SpacebuildModelPackAlpha2>Data, Lua, Materials, Models, Settings, Sound
The first time(ive done it twice now), i moved the respective folders stragith into garrysmod/garrysmod, and merged them. The second time, i put SBMPA2 into addons. Before i try another, i figured id just ask. Thanks.

you should just have to put the sbmp folder in the addons folder. I use svn and export it to the folder.
