Did you try it with/without the '-' ?

Oh and if its Half-Life 2, you will need to install the game using the disks first, and then register/unlock the game to steam.

I did both things u said...it still says that

[Krovvy]

Well I really can't help you too much then. You can try asking at www.steampowered.com in their forums. You did purchase your Half-Life 2 from a store right?

[[Koolaid]]

[Krovvy]

Have you already registered it before to another steam account?
