I am not sure what to say about the 0 byte transfer other than other gui's using the exiso.exe had a similar issue, as did I at one point. Make sure you are deleting the incomplete game folder from the 360 before trying to use the app again.
The problem cleared up for me some time ago and I have not seen it since. I have tested this in FSD, FSD2, and xexmenu, 100% success with all three.
Post back what ends up resolving your problem Kunzinator.
Again, im glad you guys are enjoying and getting use out of this =) I will probably work on a button to view batch jobs or something similar for a next release.
