i dont think that it is the start .exe... i run wpi from a dvd using 'runwpi.cmd' .... it might be me running a cleanup .cmd at the end, but i doubt it... it looks like the install has lost its 'path' at the end, then desides to crash as it cant find the rb_config.js, then it just hangs... if i knew what file the code is contained and what part i may be able to correct it, but as yet i cannot find it... thank you for your time, its much apreciated..
