Help! My DVD drive won't read Strad disc

[amcmechan]

I got the Strad discs a couple of weeks ago, loaded them up just fine. Then, having read some of the issues on this forum, and having some initial small problems, I decided to delete and then reinstall the program. Delete went fine. However, when I went to reinstall, my DVD drive would not read the Strad disc. It acts like there''s no disc in the drive. BTW- it works fine for all other discs, so it's not the drive, which is new.

Whassup? Anybody got any help to spare on this one?

thx.
