Cause of the new exiso.exe the program is broken now.
To fix it open IsoTo360.cmd in notepad (right click - Edit) and search for this line:
exiso -d %gamesDir% -f %ipAddy% -s %rarLoc%\%isoName%
Replace it with:
exiso -d %gamesDir% -f %ipAddy% %rarLoc%\%isoName%
The reason you must do this is the new exe he has packed no longer supports -s and causes exiso.exe to just error and not do anything. I'm not really sure what -s is meant to do since it is no longer in there though.

But recently i have had issues. I tried transferring an iso to the 360 and the screen flashes for a moment and disappears. I thought it was the iso so i tried 2 other games and i get the same issue. I unrared the rarto360 again thinking the files got corrupt but same issue. It was working perfectly fine last wk. I even updated to the latest java. Nothing has changed on my pc, i have no AV or anything, as a pc tech i dont needed i rarely get any. Why would all of a sudden it just stop working? I am probably gonna try another pc later on, but i want to figure out why it works then all of a sudden nada
