Help with Achtung Panzer: Operation Star and updates

[Stealhead]

OK I just purchased Achtung Panzer: Operation Star from Gamers Gate I am a little confused on the updates I D/L one it says:

1) Unpack update to any folder.
2) Install game core update 5.77 for this run op_star_game_update_eng_v577.exe.
3) In the window that appears, click "Install" button and select "CORE\desc.addpack" file
in folder with unpacked update.
4) Wait for the installation.
5) Click "Save and Play" button.

Now I click next and it goes to the file location it does its thing and then I click finish and the installer closes then it opens this game updater deal and I am supposed to I take select an add on but none are there to select :hmmm:. None of them update the base game?

I have not yet D/L ed the expansions though so maybe they will show up here after they are installed?
Thanks.

For the others,

1) Dl the Core Update from Graviteam (http://www.steelfury.com/AP-STAR/op_star_game_update_eng_v577.exe)
2) Install the Core Update (I just install it in my game folder)
3) DL your .exe from Gamersgate (the Game updater should create one folder called "GamersGate temporary files" with one sub folder for each add-on)
4) Launch the game and select "Update" in the menu
5) In the new windows (Game updater) : select each file "desc.addpack" (one per add-on)
6) Select "Save and play" on the game updater
