Cant activate DFX2

[neomarz1]

I just installed DFx2 and install seemed to go fine, but when I put the disk in Single player and multiplayer are not available. only update and activate are available. when I select activate it gives me an error code and tells me that cant be activated without update. then when I try and update a small window pops up showing that the command files are being updated, it scrolls, then goes away. then comes back again trying to do the same thing again. this repeats over and over. and eventually stops. Also when i installed the game, it never prompted me to enter the cd code. I have uninstalled the game and reinstalled it several times. still the same garbage. HELP!
