The log shows that 2.994 seconds elapsed between when you started
VASSAL and when it exited. This almost certainly means that it detected
that another instance of VASSAL was already running---i.e., the one
you started first did not exit, despite appearances.

Typically when this happens, you'll be able to start VASSAL once after
each reboot, but not on subsequent tries. After rebooting next, start
VASSAL and then exit it. Then check in the Task Manager whether there
is a java.exe process still running after all of VASSAL's windows are
gone. Is there?
