CD Key invalid(steam install) help

[michaelsenna]

Hello,
I just bought BF2 so I could play PR but I can't join any of the servers because it claims that my CD key is invalid?
It says "Your CD is not valid. Please check your CD key is valid in Launcher -> Support -> Keys"

When I go there the code looks nothing like the one there is on steam but I can't change it for some weird reason

Thanks in advance. I hope to see you guys on the battlefield,

OPen Steam Client, verify the integrity of your BF2 installation. It iwll probably redownload 3 to 7 files, which should fix this problem.
