Gcombat and PHX3 won't work

the title says it all. i got problem with makeing phx3 and gcombat to work. then i start the game and go in singleplayer, its not there! how do i solve this problem?
both are in addons and i dont know if i need to do svn checkout with both. if i have to, would you plz write the URL for both?

You don’t need to use SVN, but its recommended. As long as you have the downloaded addons unzipped in your addons folder, they’ll work. Unfortunately, I don’t know either SVN.

For PHX, see http://www.facepunch.com/showthread.php?t=688324
For Gcombat, see http://www.garrysmod.org/downloads/?a=view&id=35442
If you’re using a pirated version of Gmod, see http://store.steampowered.com/app/4000/

could be a case of double foldering. When you open the addons folder -> PHX do you immediately see the info.txt file?

found out what the problem is. then i unpack the stuff they appear with 2 folders. the first with the second folder, and the second folder with the contents, so all i had to do is to remove the first folder and place the addon in addons! now all my stuff works!
thanks for the advices anyway
