Hi, Just got a Plextor PX-708UF2 external DVD burner. Hooked up to my laptop through USB 2.0, running DVD Shrink and Nero, and having mixed results, so I thought I'd upgrade the Plextor firmware. Downloaded 1.08 from Plextor, try to run it, and it says "no drive found." ?!?! I know the drive works, because I've backed up several movies with it. Thanks for your help.
