Image will not mount...

[r_bayonet]

Here's my setup: I am using DVD Decrypter to convert dvds into ISO files then use DT to mount them in a dummy drive, and burning them with 123 Copy DVD to burn it into a "backup".

Here's the problem: everything was working fine for a long time but suddenly aftr I mount the image to the dummy drive I open 123 Copy DVD and it recognizes the drive but not the image that is mounted. So I re-installed 123 Copy DVD, and still it would not recognize it, I re-installed DVD Drecrypt and DT also and now it will not even mount the image, it says "Unable to mount image. File not accesible.". Please let me know if i'm doing something wrong, and if possible recomend other programs I could use to get what I need.
Thanks,

Unable to mount image. File not accesible.

Did you try to open the ISO with a tool like UltraISO? Maybe the hard drive you store it on is wrecked or something else is wrong? Don't blame it on DT for now
