I don't know what made it work, but I was able to play with my Intel 945GM graphic card now. The texture limit was not the thing. Again I turned off one of my two screens, and suddenly it worked.
I'm not sure if my problem on the Windows version is related, but I don't understand what's happening in the updater_log.txt and it sounded similar and appears that it crashes as soon as it tries to get the first png file from the data.jar. Can it be that the arguments for the launcher got corrupted in multiple versions somehow? Or a path changed in the archive? I can locate that file in the data.jar, but the game doesn't start. Here are the top lines from the updater_log:
23.01.2010 11:40:17 com.turborilla.mule.launcher.Launcher run INFO: Arguments: lib\jre\bin\java.exe;java -Xms64m -Xmx256m -Djava.library.path=lib -jar data.jar 23.01.2010 11:40:17 com.turborilla.mule.launcher.Launcher run INFO: Classpath: C:\mule\data\launcher.jar 23.01.2010 11:40:17 com.turborilla.mule.launcher.Launcher run INFO: Java VM: 14.0-b16 23.01.2010 11:40:17 com.turborilla.mule.launcher.Launcher run INFO: Java Runtime: 1.6.0_14-b08
Maybe these two problems are not connected, then please move this to the following topic, where it might fit better then.
I use the current Windows download and can't get it to start, neither with login nor a local game. It always get's until the point, where the screen turns black for a very short time, then a box appears with a message, it couldn't load some file "Failed to load image from images/followers/sprite-mule.png".
Snippet from log.txt:
INFO [View.<init>] Creating view... SEVERE [SlickLogSystem.error] java.io.IOException: Attempt to allocate a texture to big for the current hardware
I updated Java, the Intel graphics drivers, I searched the forum for this, but couldn't figure what it is. I use two screens but I turned one off and that didn't help either. Anybody an idea? I attached the logs.
