When done that, it just said complete and closed. Is that supposed to happen?Have you verified the integrity of CS:S' game cache yet?
If not, and you don't know how, just do the following:
1. Go to your steam library, right click CS:S
2. Select properties, then go to the Local Files tab
3. Click Verify Integrity of Game Cache
Doing this makes sure that all your game files are ok and not corrupt. For you it will probably find a problem with one of your files and fix it for you.
Hope this works for ya,

Yes I beleive so!
Have you tried restarting steam and/or your computer?
If nothing else has worked so far you might need to re-install CS:S.
Please respond quickly.
