JACK problem has me re-booting more often than Windows

When JACK crashes (which is VERY often) it won't restart unless I reboot the computer. I downloaded the image for 64Studio live version, then downloaded the installation DVD and installed from that. According to the update manager, there are no new packages to load to update anything. My hardware: Gigabyte GA-7ZX motherboard AMD Duron (I think a 900 or 950 Mhz) 512 MB RAM NVidia Graphics card On Board Creative sound PCI sound card SB24 Live 200 GB WD EIDE hard drive (master) 120 GB Maxtor hard drive (slave) Here are two JACK message dumps the first is a successful start after a reboot (verbose output is on): **************** start of paste ****************** 3:58:00.338 Patchbay deactivated. 03:58:00.644 Statistics reset. 03:58:01.263 MIDI connection graph change.

That, obiviously, would save me a lot of time. Thanks.
