It now works fine for me.. (win 7 64bit) had to do a couple of things... I installed the app on my n900, it runs fine on my pc I extracted the zip file to a folder on my desktop, here is where I started having problems, i would run.bat but it would last half a second and closed right away, with the use of print screen and good timing i found out that it coundt find Java to run, so I went to the java folder in program files, copied java.exe to the folder i extracted the onedotzero files, and it ran... but...... black screen nothing happend.... alas I tryed hitting the Windows button and clicking the minimized icon on the icon bar until it suddenly started working.. after that all ran smooth and cool. just wanted to let you know it does run, just needs a bit of tweaks and patience
