I did a little bit of research on this issue. I seem to be the fourth person affected by this problem.
On first sight, the problem is that I have two versions of the program working at the same time. The fact that I can't delete the program without killing the jawal.exe process also points toward this. However, when I do make a fresh install, I get the window where it asks me to choose a language and a voice. After that, I get nothing. The new log file I get is similar to the one I posted with the "
java.lang.NullPointerException
at hu.belicza.andras.sc2gears.services.InstanceMonitor.run(InstanceMonitor.java:105)"
lines missing. I'm not getting my hopes up too much, but I would love it if you could find a workaround for me.
