Ok now I understand it ...

But please tell me so where can I find Any some kind of list IP adresses of games that I could join to play multiplayer?

http://www.nwnlist.com/

Here, you can find most of the good worlds for both NWN1 and NWN2

Since you mention NWN2, I should point out that direct connect is not the only way to join a server in NWN2. You can do it through the Gamespy menu as before if you install the NWN2 Client Extension, because the extension replaces the Gamespy list with a new working one.

Ok thx I have found this server list but I have one more problem (I hope the last one).
When I am trying to connect to any game from the list by direct connection it says that server version and client verions arent the same and connection has failed.
Perhaps I am too stupid or too old to solve this by myself :-(
What and how to do now?

Most (if not all) servers use the latest NWN version which is 1.69. If you installed the GOG version you should be up to date. However it is noted that some languages does not have the latest version.

To check which version you have, run NWN. On the main page (where you see New, Load etc) click Options. On the right corner of that screen it will tell you the version. Mine is 1.69.8109.

If your version is lower than 1.69, you have to find the critical patch which you can find the link in this forum.

i have the same problem :(

I believe you can find the 1.69 patch here.

The game client is 1,69,8099 so what version have online servers ???

Visit the webpage for the Server you want to connect with and read what they say you need to get started. Many persistent servers have extensively modified they game, and you need to have their mods to play.
