I am going to post the same on the Steam forums, but I wanted to know what to do from people here as well.
Ok, here's what happened;
From longing to play NS once more, I managed to get another CD-Key from the store where I bought my HL:Platinum Pack, since Steam said my last one was in use. (Yes I know I'm weak, but I can't resist the temptation of playing NS)
So now, I've got Steam downloaded and everything set to go. I click on the "Browse Games" button, go to "Register a product a I already own".
Once more, I'm faced with the vile "Enter your CD-Key" screen I've despised so much. I enter my CD-Key.
Everything goes fine, to my surprise! Now I shouldn't have gotten excited 'cause here comes the bad part. (And also because it's Steam)
Alright, CD-Key entered and registering completed, it gives me this:
"Steam is unable to complete your transaction, due to the servers being too busy, we will get to you as soon as possible once your subsciption is complete.
Meanwhile, you can play Half-Life: Platinum Pack."
Or something like that.
Releaved, due to the fact that I finally get to play in Steam (shudder), I procceed onto the next screen.
It asks me what games I want added to the "My Games" list, so I select and proceed further.
As soon as I get to the next screen an error pops up saying-
"Your download cannot start because the servers are too busy, please try again in a few minutes"
-and it quits to the main Steam screen.
Awestruck at the stupidity of the moment I go to check my games list and it was just like before! No games, no nothing!
In panic that the games should appear later in the list I tried joining a server but it pops me back to the browse games window, as If I never made a subscription!
My question is "WTF JUST HAPPENED!!?"
