I have an iRiver IFP-995 flash player with the accompanying Music Manager software. I have a January (2008) Mac Pro. I updated from 10.5.5 to 10.5.6 yesterday. Since doing so, every time I connect my iRiver via USB, my mac crashes with a message telling me to restart the computer. I can connect the iRiver fine, but it crashes when the software is open and I turn the iRiver player on so the software can read the player. Has anyone else experienced this problem, or can anyone offer some troubleshooting suggestions? Thanks, everyone.
