CD-RW unrecognized since X.1

[infinityBBC]

i've been burning CDs with OSX with my new firewire Plextor with Toast 5.0.2 with no problems. since OSX.1, Toast cannot recognize the Plextor, however the Apple System Profiler sees it, along with it's , but says "Not available".

anyone know anything about this?

also... i'm having address book troubles with "groups".
