A hotfix patch has been released for Commander - Europe at War to fix an issue with Java.
8th July 2008 - Commander - Java Hotfix for 1.06
We've had a number of people reporting issues with Commander - Europe at War v1.06. After some checking we've found the issue seems to be related to a recent Windows update for Vista & Windows XP. For some reason support for parts of the Java library that were used in the game no longer work in this windows update. We've changed the version of Java we are using and our tests so far show that this version is still supported by Windows. These kind of things are totally out of our control, but we'll do what we can to keep you running! Please report any issues in the forum.
If you are not experiencing any issues you do not need this update, as it does not change the game in any way, it only fixes a crash bug or load/save issue on some machines.
