In order to launch files from the F drive, you have to double click them from your computer. You can't actually browse them from the xbox, just the comp. I would say that it's probably the pbl causing nothing to show up. why not use the debug bios all the time and put your dashboard in the tools folder. Only problem you might find is Halo. (Won't play unless you turn debug off) and one other game, can't remember which one. Use PBL to load a different bios that way. You could even use the dashboard.xbx file to run evox, or maybe edit it to run a different dash. That would be cool.
