lol so in this case it is 3.0.9. But I trie other forums with other emulators and they never used the name of the package as the client version.
So ill upgrade my client to 3.0.9.
Still got the question about updateing the server core. Is this realy nennessery? Or just in case you want to upgrade to a leter client version. (i'm so carefull because I had to do 2 complete new installations. Realy want to get this working once in my life
