Now I can't install SH 3!! why why why :(

[artao]

On the off chance anyone here will be able to help me with this issue, my frapping dvd drive won't read my SH 3 disc anymore!! Or, apparently, any other DVDs properly (I only see the video_ts folder, no audio_ts). This freakin drive is only about 6 months old!!! I only started having this problem after I had to completely re-install windows due to a virus (which I've now had to do again, on a completely physically different hard drive) ... I sure hope that didn't pooch my DVD drive. It reads regular old CDs just fine, just not DVDs. When I insert the disc, it 'reads' and comes up as 'SH3', but the only file visible on the disc is 0x0409.ini. Sometimes it comes up as 'Silent Hunter 3', with the ability to autoplay, but when I try to do so, it asks me what program I want to open it with, and still only the aforementioned file is visible on the disc.
WTF!!!! why why why why why??? :d own: grrrrrrrrrrr
I have tried Win XP support site, even allowing the Mr.Fixit app to run, and it says it fixed the problem, but it sure as hell didn't. And apparently MS wants $50 for me to e-mail them for tech support.
-sigh- <breathe calmly>
ok, thanks ... if no one has any ideas on how to fix this, I guess I'm just venting .... but this is VERY VERY frustrating as I was very much looking forward to some SH 3 after all the SH 5 flap, viewing some Nat Geo show someone posted, and trying to get Danger From the Deep to run (no go for now) ... and now I can't!!
-sigh- maybe I can get SH 1 to run, or maybe Wolfpack ...
