I have run my JB3 for a couple of shows with the newest firmware. All glitch free. I am now having problems getting my PC to recognize it though firewire. I've tried reinstalling the file manager, but no help. What is the latest firmware you guys are using that is recognized by the current file manager? I don't really want to go back in firmware revisions because the newest version is nice, but why wouldn't they make sure it works with their programs?
