When i am to select components to install,
there is only one wich name is Mod Files to install but the check box cant be checked... is it something that needs to be installed before the Full Version (1.0) or is it something else?

Its a EXE File btw

It might be caused by Steam not being installed into the default directory. If it doesn't work, try the ZIP version.

I downloaded the zip file but the map i need to extract the stuff from is empty



?!?

...Wait, are you saying the .zip file is corrupted?

The Combine Destiny folder should be extracted to
steam\steamapps\sourcemods

nothing there from the EXE and nothing from he zip

wehn I began installing mods I made the mistake of unzipping into a folder in Sourcemods.

So, instead of having the gameinfo.txt here:

Steam/SteamApps/SourceMods/CombineDestiny/gameinfo.txt

I had it here:

Steam/SteamApps/SourceMods/CombineDestiny/CombineDestiny/gameinfo.txt

That won't work. So, make sure you have it correct.

Also, to play the game you need a source game. It doesn't matter which, as long as it isn't a game that you got with an ati graphics card or any other similar sort.
Make sure you have Source SDK Base installed.
