Half-Life2's Scripts folder is being a real pain in my ass.

[WishesForFishes]

So I've noticed that since the mac update for hl2, the scripts folder just died.
It works perfectly fine for episode 2 and every-other source game except hl2.
Now if that doesn't make sense let me explain.
The folder where scripts go in to replace what sounds or model a weapon uses, or maybe what dialoge the NPCs might say. Located here:
C:\Program Files\Steam\steamapps\USERNAME\half-life2\hl2\scripts
Ever since hl2 was updated, nothing placed in this folder works.
It just wont override what's in the GFC.
I'm not a moron here either, I've been screwing around with the source engine for a good while now and I know how alot of it works.
I've tried every obvious solution so far and when ever I go to google this issue I find nothing helpful.
So I figure it won't hurt to ask what the hell is wrong with my game.

It short, source is failing to detect the scripts folder. How can I fix this?

Have you tried reinstalling?

[WishesForFishes]

First thing I did actually.

The golden rule is:
If it's broke, reinstall before asking for help.

[Gook Nukem]

Uninstall it, delete all the game folders, make sure there's no trace of it, reinstall.

[WishesForFishes]

Did that too.
That is kind of what reinstalling is.
