u don't need to get ur program launch like that for using the neowpn dekstop icon or menu icon just go to terminal in n900 and typing that:

sudo gainroot
chmod +x /usr/bin/neopwn.sh
chmod +x /usr/bin/neopwn

and now its great no crash when u launch with the program icon

if u have another question ..............

for who not having the files for installing the beta i can upload it ... just tell me ??

why wanna upload it cause it's very very very beta beta only have injection and metasploit (metasploit can run without neopwn in n900 and paying 40 $ just for the injection it's not like what im thinking about OPEN SOURCE so .........
