how do i install life support 3?

ok

i did have all the individual addons in but as that didnt work i got the full version
i downloaded the full svn (with everything) and whacked it into my addons folder

i named the folder life support
it has all the other folders in it

i also tried deleting two of the folders as they stated they dont work (damage systems and something else in alpha) (this was after my other attempt failed

it doesnt work

what do i need to do?
