When I said drivers, I meant firmware... It seems like there are no firmware updates for this drive.
I tried cleaning the disc, and I ran the Microsoft utility, which fixed *something* but it does not appear to have fixed the issue I am experiencing with Myst V. For tonight I'll have to stop and see what I can do when I get back to it.
Is there much of a chance the game would install successfully with a new CD ROM drive? There are USB drives that are very, very cheap.
