First make certain that your system can actually read the cd. I guess the easiest way to do this would simply be to copy the files into a directory on your hard disk. If you succeed you might then try importing them into Bryce from the new hard disk copies. As Bryce doesn't modify the files during installation the read/only file attribute probably won't matter. (BTW, if you select all the files you should be able to change this attribute for all of them at once- at least under Windows.) If you can't read them it is possible that you set up multiple sessions on the cd and you're in the wrong session. I don't know too much about this as I never use multiple sessions. It might also be that you didn't close the cd when you burned it. Sometimes this means you can see the directory structure but can't get at the files. Check your cd burning software to learn more about this. As a side note I do not recommend RWs for long term storage as they are not as reliable as CDRs. I tend to be somewhat sloppy except when it comes to computers wherein I become positively anal. After burning a cd I immediately do a byte by byte file comparison between the cd and source files. (you can find such programs on the web) If there is a problem I want to know immediately so I can solve it- not a few months later when I will be screwed. I also make duplicate cds and keep one of premise- if I have a fire the cost of replacing my software and data is far greater than that of the hardware.
