How many sub 1200 players with over 1000 games are there that read the forums?
Why would the client need port 8080 not like it is a web server???? Maybe it is miss-configured to run a web server??? Introducing new libs can have this effect.
Your problem is not similar at all :D... He has a game issue. You have a client issue
Maybe change the language to English.... I read that some translations caused crashes last release
Your sentence has grammatically errors which makes me unable to understand what you are trying to say
The solution for this would probably be really complicated right? I mean there are so many maps out there in various version to calculate rating you would need a huge amount of games. Showing the times a player played a map is probably doable. I saw some site where you could display how many time a player played what map.
