I wanted to download the free CryENGINE 3 SDK thing, so...

I downloaded the .zip file on http://www.crydev.net/dm_eds/download_detail.php?id=4

After the long wait, when I open "CryENGINE_PC_v3_4_5_6666_freesdk.zip", this message will show up.



Can someone help me? I may sound like an ignorant idiot, but I apologize for my little knowledge about the game engine.

Thanks.
