Can anyone please help me.

[SuperNaraku]

I have downloaded steam and i clicked on 'activate a product' i put in the CD Key and i get this message that says. Your subscription to Half Life Platinum Pack has not been completed, because Steam Servers are currently unable to process this transaction. I don't understand this, can anyone help me?

It means Steam is having problems. Try again later when Steam is working.
