You did actually install Siege of Dragonspear after installing Baldur's Gate: Enhanced Edition, right? I don't mean to sound flippant -- it's just easy to miss that SoD is a separate installer from the main game.

If you have just BG:EE installed, the game's background/theme will look like grey stone. Once you install SoD the background/theme will look like black dragon scales, and you'll have an icon on the game's initial title screen with the SoD logo right next to the Black Pits icon.

Well thank you Ryan but i try something else like i downloaded it on the GOG site and im sure it will work.

But i'm wondering why it didn't appear on GOG galaxy own games list, even in extras and goodies.

EDIT

Well after dld the SOD on the website it still v.2.5 so the game dont recognize the game properly

ok, i contact the support and they told me to check my account on gog.com to see if the games was available on my list, absolutely yes, and they asked me to close galaxy and use this link: www.gog.com/user/refresh and miracle after i start galaxy i've beginning dowloading my missing files from SoD

Hey there, I had the same problem.

You have to click on Baldur's Gate in GOG application on your computer, and then go to EXTRAS - downthere you have SOD to dowload.

caused me a lot of trouble too.

is SoD suppose to be included in EE or is it a separate purchase??

Siege of Dragonspear is sold separately. You must have Baldur's Gate: Enhanced Edition to play it, but you can play BG:EE without SoD.
