Hello!I can't get arduino IDE to work. Each time I try to start it I get "launch4j" error. IDE does not open, and haven't been working since i've downloaded it. I tried reinstalling java and using patched pde.jar and rxtxserial.dll. Deleting preferences doesn't work either, as I haven't even started IDE yet According to troubleshooting guide I should open run.bat, but I can't find it anywhere (downloaded IDE twice, still nothing). Any help is much appreciated.
