Okay so... these are the bugs that are common in windows 7 (aatleast I think they happen to me a lot) :
When I click the play Ace of Spades it goes to the page but says it can't load it ( this goes for google chrome , I don't know for mozilla or explorer) the error looks like this : Oops! Google Chrome has failed to establish a link to the page www.ace-spades.com , the first option is this : Access to copies of the cached pages www.ace-spades.com/play/ , click it and you will see all the servers from the last time you were on the page , and if some don't work they are obviously not there anymore , but you can still play.
And the other is when you go to a server it loads kinda faster then normal ( to me it's like this ). When the loading is finished it exits the game and sayas that client.exe has stoped working. I just went to the instaler and clicked repair. It worked .
Also when your game works the voxel editor and server.exe won't. But when the game is saying client.exe has stoped working the server.exe works and voxel editor is working ... I hope you fix 'em soon !
