Hang Up On Import

[lpwalsh]

I just upgraded to 3.310. In my show computer I have the Plextor PX-W8432t. In my backup computer I have Plexwriter 24/10/40a. Both drives cause a system lock up on an import. The only way to recover is by holding in the power button until the computer shuts off. Two different computers, two plextor drives that worked fine until the upgrade. Fortunately the DVD-rom drive in my backup computer will work but the one in my show computer will not. No lockup, just wont read the disk. I brought both computers up to date on Microsoft updates, before upgrading to 3.310. Am I going to have to choose between buying two new drives or the upgrade?? What gives??
