Manga Studio error occurred while trying to mount a disk

Hello,
I just downloaded Manga Studio Ex version 4.0 and trying to mount a disc using this software but I am unable to complete this task successfully. The following error displayed “Manga Studio Ex Ver4.0 Disc is not inserted into the CD drive. Set the Manga Studio Ex Ver4.0 Disc into your CD drive and press OK”. Provide me the solution or advice to fix this issue.
Manga Studio Ex Ver4.0 gives me the following error message while I have inserted a disc into the CD drive. Why am I getting this worse error message using Linux OS. How can I solve this problem without having any trouble? Any idea would be appreciated. Thanks in advance.
Thanks.
