operation flashpoint patch: problem

[hatsu]

hello everyone, i am sorry if my request seems to be stupid but I am a newbie in this kind of things.

So, my terrible problem is: I installed Operation Flashpoint (EU versrino, so 1.00), i downloaded the patch to update the game to version 1.10 but the setup tells me that I do not have the originalk cd inside. The .exe file is the original one (i didn't apply any kind of no-cd fix).

What can I do to install the bloody patch?

Thanks for your attention,

bye
