Mein Problem ist, dass ich den Launcher zwar öffnen kann, Minecraft aber nicht startet. Heißt, ich kann mich einloggen und wenn ich auf 'Play' drücke läd der Balken unten auch ganz normal. Dann öffnet sich das Fenster vom Spiel für einen ganz kurzen Moment und schließt sich daraufhin sofort wieder. Dann geht der Launcher wieder auf. Wenn ich dann auf 'Development Console' klicke steht dort folgenes:

Ich habe meinen Account for etwa zwei Jahren gekauft. Da hat das Spiel auch noch funktioniert. Vor etwa zwei Monaten habe ich dann ein anderes Betriebssystem auf meinem Laptop installiert und jetzt geht es nicht mehr. Ich habe jetzt Windows Vista. Auf dem Laptop meines Vaters, welches Windows 7 hat, funktioniert Minecraft auch nicht.
Ich habe schon auf diversen Websites geschaut. Dort hatten Spieler ähnliche Probleme. Die Antworten waren größtenteils unterschiedlich und ich habe versucht so viel wie möglich auszuprobiern. Meine Java Version ist übriegens auch auf dem neustem Stand.

Ich hoffe sie können mir weiterhelfen.
Danke schon einmal im Vorraus.
