Help. corrupt viola file

[maan]

Gentlemen,

Would you please suggest for me some books, and or software, for someone trying to learn composing by himself, and he is very beginner.
One another help if possible. I just purchased Horizon Opus.1, DVDs. Everythything went fine installing, one exception: (05 viola-standard.gig)
My DVD drive can't read this file from the disk, and its skipping it.
I really need this file.
Any help on how can download this file, or a link or anything, is highly appreciated.
again I only need this file, everthing else no problem. Thank you.

Regards,
M. Mozayek.

Hi there Maan. What you should try is to manually drag the 05 viola-standard.gig file from the dvd drive to your desktop. This may solve your issue.
